problems setting up DSL / DHCP server unreachable

Question: problems setting up DSL / DHCP server unreachable


I've been looking all over the internet to try and resolve this, but I couldn't find a solution... here goes:

I've been unsuccessful in trying to set up my Verizon DSL connection. According to Verizon tech support, the phone line is fine and my problem in connecting lies at home.

The details:

-I haven't been able to run account setup for my DSL service because I'm getting a problem in connecting

-I'm running Win2k

-I'm connected to the DSL Modem with a Belkin NIC

-The connection shows that it's active, BUT it only sends packets, doesn't receive them.

-When I ran ipconfig, my ip was in the range, and Autoconfiguration Enabled read Yes

-When I went to release my IP, I got a message that said
"All adapters bound to DHCP do not havee DHCP addresses. The addresses were automatically configured and can not be released."

-From the Microsoft web site, I followed instructions to disable APIPA found here ->microsoft support link

-Now ipconfig reads my ip as all zeros, and I get an error when I try to run the command /renew that says the DHCP server is unreachable

Thanks in advance

I have had a network for almost two years with no problems, and for some reason my laptop has not been able to get online for about a week. It did this once before last year sometime, and I phoned Bellsouth; they said to shut down all the computers and then restart them, and that fixed the problem. It did not help this time.
I have tried everything I can think of.

My laptop is a Sony Viao with Windows 2000. I am using a Linksys router and wireless card with my Bellsouth Westell DSL modem. Someone else set up the network for me, but I don't have contact with that person any more to help me. I will probably phone Bellsouth again, but thought I'd try this, too. I tried Linksys' live chat but they kept getting disconnected.

When I type in ipconfig /release it says it's already released. When I type in ipconfig /renew it hangs a long time and then tells me that the DHCP server is unreachable.

I have three computers. One is this Dell I am currently typing on, with XP, and it is connected directly (wired) and works fine. Sometimes the connection goes out and I have to unplug the modem and plug it in again and then it works fine. That has always been true, though.

I have another Dell, an old one with Windows 98, and it is wireless. We don't use that one very much because it's slow, but it has a wireless connection and sometimes it can't get online, either. It has troubles but sometimes it works, sometimes it doesn't. That's been for ab... Read more

"DHCP server unreachable" error message.
Could you please help me?

I have a crossover cable between my laptop and my home PC, with my laptop as the main computer. I have the laptop IP set to, and the Home PC to 'Obtain and IP address Automatically'.

This set up actually worked for some time. Sometimes, when I open up the command prompt and type in 'ipconfig', it gives me a 168.xx.xx.xx address, and I just type in 'ipconfig /release' and 'ipconfig /renew' and after a minute of waiting, I used to get a 192.168.0.XX address. After this, I was able to share the Internet Connection between the 2 computers, the files etc.

But of late, I have not been able to get this 192 IP address. After typing in 'ipconfig /release' and 'ipconfig /renew', after a minute of waiting, I get a "DHCP server unreachable" error message.

I have tried restaring the PC etc etc, but I continually get this same message. I can ping from the Home PC if I put in a address on the Home PC, and I can even share files.... but I am NOT able to share the Internet connection!!

Please suggest what needs to be done. Thank you!!

Any help at all is welcome.

Answer:"DHCP server unreachable" error message.

perhaps ur IP has detected this. Could this possibly be not allowed by ur ISP? If so, your ISP probably did something to keep you from doing this. Also, for better results, use a router it works much better and you are usually always garunteed 100% uptime and no problems.

Currently we have 25 servers where I work. The other day we had our one and only DHCP server go down and were not able to fix it. Luckily the other server in the cluster had DHCP setup and just needed to be set to authoritative and everything was back and working.

However the problem remains and the original DHCP server was unable to be fixed which means we only have 1 with no backup.

Because of this I need to setup a backup server incase this happens again. Would the best way to do this be to setup DHCP on another server exactly how it is on the production one and have it disabled. Then if something ever happens just make the backup the authoritative one?

If there is a better way please let me know but this is the best I could come up with.

Answer:Setting up a backup DHCP server?

Well the ultimate solution would be to change everything to static. Then it doesn't matter if the DHCP goes down.

Hello, my xp has had the "limited/no connectivity" warning for a while but it did not effect my connection at all until recently. i have zero connectivity now on my vista and xp while connected to the router. (sorry in advance I'm not very knowledgeable with networks)
Its a wired network Modem(broadband) -> router(d-link di604) -> pc1(xp)/pc2(vista)
i cannot log into my router from my browser, i cannot renew my ip from cmd as it cannot connect to "dhcp server"

right clicking on my lan network icon and trying to repair does not work because it cannot renew my ip

i have also tried restarting, disabling and enabling network card, reseting and unplugging modem and router, crossing my fingers.

all the appropriate lights are on...

im not sure what other information regarding this i can provide

any help with this would be welcome
Thank you

here's my setup:
-internet is through a westell 2200 DSL modem.
-Verizon gave us a static IP, gateway, dns, etc.
-modem is connected to a D-Link's DFL200. it's a router/fw/etc.
-i setup the D-Link's wan with static config provided by Verizon.
-i turn on DHCP server on the lan of the D-Link
-i have internet access.

the problem is that i want to enable the company network to be online as well. how do most people do it? i connected the D-Link's inside LAN to our network switch.

our network is w2k3-based AD/DHCP/DNS server serving about wxpp 20 clients. when i hook the D-Link to the network, none of the clients can get internet, but when i connect the D-link to a single client, i get internet. i've tried relaying DHCP server to our PDC (w2k3) but still no internet. is there a config i'm supposed to do on the D-Link or PDC that i'm missing?

how do people do it?

if i turn off DHCP completely, i get no internet connection from D-Link's inside LAN either through direction connection to a single client or through network. i guess these routers/firewalls require their internal DHCP to be on for internet to be enabled. that true?

i know a network can have more than 1 DHCP servers, but this one won't play nice? advice?

Answer:How do you reconcile your router/firewall's DHCP server w/your PDC's AD DHCP server?

actually, a network CANNOT have more than 1 DHCP server unless you configure different scopes on each one. if you have both managing the same leases you're going to double-book all your internal IPs and no one is going to get on the intarweb . . . . which you may have noticed is exactly what is going on here.

turn off the DHCP server on the DLink entirely. the reason your clients cannot access the internet using your windows DHCP server is because (my guess which i am 99% confident is correct) you did not set the scope options . . . specifically the one called gateway or router. this value should be set to the IP address of the DLink. it's the default route the clients will go to get to any other network other than the one they are part of.

Work in school with about 35 w98 clients and nt 4 server, recently had broadband installed so I had to change the IP address on the server as requested by broadband company then set up new dhcp scope for clients. Server reboots with new ip but cannot release and renew ip addresses on clients. (I had logged them all on ready.) Activated and reactiveted scope, changed ip back to orginal it all works but when you change it back to new settings clients can't see server, I gave one client a static address from the new range (an excluded number) and it logs on sweet as a nut - so I'm thinking dhcp problem. Also when I do IPconfig on server it gives 2 nic addresses for one mac address why?Any help would be appreciated!

Answer:nt server dhcp problems

Begining is the best solution!! hehe! So, You should do your DHCP as a new one, anyway, you were given a new IP, so it's absolutely new, isn't it!
Try mine!
Seperate DHCP from network, simply unplug the connector!
Stop DNS, delete your DHCP scope.
Uninstall, yes, uninstall you NIC!
NEXT! Do it in reverse!
Reinstall you NIC by restarting Windows! type cmd in Run command and ipconfig /all. How many NIC you have now? ( ofcourse, after you set the static IP, subnet...)
Restart DNS.
Create new DHCP scope, activevate,... ( Be sure you do it completely right).
Now, renew until DHCP work, ( Until you see the green light, you knew it).
Now, test DHCP in client by plug the connector!
Try this first!

Hi, I am using a PC (Windows XP) on a home network that is otherwise dominated by Macs, and it has been able to connect to the internet before, but it really only works when I do a full system restore where I reinstall windows and erase my HD and I'd rather not want to do this again, since I am tired of reinstalling all my crap.
Now as far as I can tell, the problem with the connection lies not in that the computer does not know how to connect to the internet, but rather that it doesn't know it is connected to the cable modem through a router. I think this because the IP address on the LAN connection is never one that all the other computers on the network have (- one that starts 192.168.1.x). I have tried a couple of times to use the network wizard, but it either says that there was an error configuring the network, or more often than not, it finishes, but the internet still doesn't work. Also, when I try to repair the connection, in the connection status window, it says it has a problem renewing the IP address, which does not work since it has problems contacting the DHCP server (I tried running "ipconfig/renew" in cmd.exe). Does anyone know how to get the computer to connect to the DHCP server?
I hope I have given enough background on the situation, if you need any more system info, please ask. Thanks in advance

Okay, so I've been getting this problem while connecting to my college dorm's network. Whenever I plug in an ethernet without modifying some settings, my computer doesn't even respond to the cable being plugged in. Going into my LAN adapter settings, I tested if a cable was even being recognized, and it was not.

The first thing I did was install a new driver for my LAN adapter, which at first did nothing. Then I started fiddling around with something called Link Speed and Duplex Settings, because it's description said matching these settings to the network's can sometimes invoke a response. Originally set at 'auto configuration', I changed these settings to 100 mbps and got a response, but didn't connect to the network. All sorts of problems come up like "Didn't recognize a DHCP server, Windows obtained automatic IP address settings". It will try to connect to the network, but ultimately takes 2 minutes or so to come up with these errors.

So next I tried the 10 mbps setting, and for some reason, this makes everything work completely fine without issues. Except I can now only get extremely slow internet speeds in exchange for internet actually working. I also tried buying a $15 NIC card to go into my unused PCI slot, but my computer won't even accept the new NIC. Booting up my computer will make it go through this continuous power restart cycles without actually displaying anything on screen.

Answer:requestion about dhcp server, some questions about planning a dhcp to a network

Is this a homework task? You can just Google  "single server solutions" and get lots of info. Is that what you want? If you want to set up a server at home or school just to learn how it works, you need to talk to the people on the Linux forum. Linux is often used as a server on a desktop PC.

one of our NT guys just brought something to my attention.

out DHCP/DNS server has an interface on the production network, as well as a backup interface (backup network)

the backup network is a parallel network (physically seperated network hardware) and is not routed/connected to the production network. it is completely isolated for backups only.

i always make sure they do not put a gateway address on the backup network (there is no router, it's a flat network), so that no traffic accidentally goes out that interface

when they did a capture/trace on the backup NIC, they were seeing packets (DHCP ACKs/replies) from the production interface.

so say the routed / production IP of the DHCP server is

when you look at the trace on the backup interface, you are seeing the DHCP ACKs/replies from source:, destination

so it looks like the server is packaging the IP header / DHCP ACK as a layer3 broadcast, and thus sending it out every physical interface.

does anyone know why the server would be doing this, and not just sending out the DHCP ACK on the interface it received the request on?

Answer:DHCP server broadcasting DHCP acks out all interfaces?

Do you know the Server OS and DHCPD name and version (if not Windows)

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

I am currently in the process of setting up a Win2000 server on my home network which consists of four other 2000/XP machines.
The server is going to be configured as a domain controller and will utilize the Active Directory.

Should I use the Win2000 Server DHCP or stick with my wireless router as the DHCP server? What are the advantages/disadvantages to both and which would be easier to maintain.

Is a 550mhz PIII with 256MB RAM fast enough to make a good home server running Win2000 server?

The server is going to have (2) 120GB Western Digital 7200rpm drives with 8MB cache for storage and a single 60GB Western Digital 7200rpm drive for the OS and few other applications.

The server's primary function is to serve as a media server with an approaching 10GB of MP3 and music video files which is continually going to grow. Disk contention is at a minimum since there are only four PC's on the network. There will also be a lot of digital photos stored on the server and will also serve as a place to perform backups from the other four networked PC's.

Answer:Win2000 Server DHCP or Router DHCP?

We have a similar setup in our office using Small Business Server, a public IP coming into our router with DHCP turned on, connected to a NIC in the internal DHCP server (which is also running ISA). A second NIC in the server bridges to the internal hub to provide DHCP services to the clients. This way we control port filtering in 2 places and with 2 levels of NAT taking place we feel secure. It may be overkill but we're concerned that EVERYONE is trying to hack into ISA and DHCP servers connected directly to public IP that this setup provides an added level of security.

Dear all

Not sure if Networking is the right category for this, but here goes...

We have several Windows Server 2003 boxes in a remote hosting centre that we connect to via Remote Desktop Connection from our offices. At the end of each working day, it's usual practice simply to close the RDC window, and in the morning we can reconnect to the same session and quickly resume working. But on a regular basis, one of the boxes (let's call it W2) becomes unreachable by morning, as in, it's unpingable and to all intents and purposes no longer on the internet.

To resolve this we can use Terminal Services Manager on one of the other remote boxes (let's call it W3) to connect to the problem box and reset the session. But we can only do this from W3 - none of the other remote machines can see W2 at this point in time. When the session has been reset, W2 once again becomes reachable remotely.

The Event Log shows up various suggestions but none of them are conclusive. About a week ago I had this, with a Source of "TermDD", which I thought looked promising:

Event ID 50
The RDP protocol component X.224 detected an error in the protocol stream and has disconnected the client.
But I've not had it since and the strage behaviour has continued.

Not really a "problem", but I got to thinking...
Sure- I can get email notifications on my phone if a UPS has lost power, or if the server is under heavy loads and whatnot- but how do I tell when the server is unreachable- for ANY reason?
Say the UPS fails, the NIC fails, or any other reason. How can I be notified of it? The server is down, so obviously the email wouldn't originate from it.

That leaves me to wonder- how do you tell? I'm thinking there has got to be some sort of software somewhere that you install on another PC (maybe the PC and the Server) that talks with the server to make sure it is up. If it is unreachable- it issues an email notification.

That of course brings up a problem to my mind- what if that other PC (workstation or whatnot) is at fault? In other words- the server is fine but the client PC's NIC failed? I would get a false alert. In which case I would need a third PC in the mix to verify results of the other two...

Just brainstorming here- anyone have any ideas?

I am new to networking and this is the first time I have tried to set up any servers and I am self-taught so you have to make things simple for me to understand. Thank you.

I have two window 2000 advanced SP4 servers I am setting up at a Christian Academy. Everything worked good until I upgraded the second server to a DC. Now I can't access any files on the opposite server.

EXP. If I am on server #1 and try to access the shared files on server #2 I can't access them. I could before I upgraded server #2 to a DC.

I can't connect clients to the servers, I could before the upgrade. The only way I can get the two servers to share files was to give permission to each to access the other and I know this isn't the correct solution. This just allows the servers to share files but doing this won't allow clients to access the servers.

I've tried on a client to demote the domain to a workgroup and then back to a domain but when I do the server (domain) can't be found error appears. I've reset DNS on servers and on clients but no help.

I would appreciate any help solving this problem, I have one week and the staff will be back to work and they need to be able to logon to the network.

Thank you and have a great day.

Answer:Problems after setting up DC on second server

When you ran DCPROMO, did you create a new domain by chance? or add as an additional domain controller?

The original server you have would have held all the roles for the network, the second DC will be an additional. Was this the case on your setup?

Download the 2000 support tools here:

At the very least, run dcdiag /v and post your results. List the server names for your first server and the addon DC.

Cerberus on my main machine picked up a connection was getting established...but it never went further...and the WINSCP connection I had timed out.

So something isn't getting through or established. Based on all that info, any thoughts as to why? The Cerberus installation setup said that Port 20 needed to be forwarded for outgoing traffic (which as stated above, I did).

FTP over SSL is not SFTP
SFTP = File transfer over SSH
SSH = Secure Shell

FTP over SSL is FTPS

WinSCP is for SFTP and SCP, both are SSH based protocols

News flash, Windows media player in Windows 8 can not play DVD's or stream them, there is no built in DVD player in Windows 8 so it's not broken, they simply removed the functionality, it can do music but that's about it.

I use Windows Media Center for streaming.

I'm running Remote Server Administration Tools (RSAT) on Windows 7 Professional 64-bit and I've noticed that when I run the DHCP Management tool (DHCPMGMT.MSC) and I add our DHCP Authorised server then close the console, it forgets the DHCP server and I
have to re-select it next time I use the console. 
On the other hand, the DNS console remembers that I've used a particular DNS server even after I close the console.
Wondering why the DHCP Management console is so forgetful?

HiInstalling a Netgear PS110 print server for 2 parallel printer and 3 computers (all XP) on a 3com wireless adsl router 3crwdr100u-72. Everything installed and works fine for the main desktop, but trying to use the netgear 'add printer' wizzard on the laptops doesn't go smoothly. The desktop setup, using ethernet to router, router LAN port to print server works 100%. When trying to install on laptop, one doesn't seenm to run the add printer wizard properly as it revert to the windows add printer wizzard asking for the printer location and not telling me like the desktop did with the netgear wizzard.The other laptop says 'cannot add printer port' so gets stuck there.Do I need to (checklist) have the computer all set up as if I was running ordinary file and printer sharing on a network, since the desktop just worked straight away?

Ok Folks here is what im working with:

Single server - Active Directory
and about 30-40 users. We currently use static IP and it is annoying me to no end. Is it applicable to use DHCP in this setting? And if i keep some of the static devices (switches, servers, etc.) as static, will DHCP "skip" those IPs when it's handing out numbers?

Any help would be good.

Answer:DHCP In Corporate Setting

A) DHCP is great in the enterprise. Control addressing, routing, and name resolution on one system, then propogate that info to all clients autoamtically. No more worrying about a typo in a statically set IP address, accidentally setting the same address for two machines, etc.

B) You can create lease reservations, where a DHCP client gets the same IP address everytime it boots up, and you can also exclude addresses from the DHCP address pool if you have devices that require static IPs, such as network print devices, DNS servers, etc.

C) When you install and configure the DHCP service, don't forget to have an enterprise admin authorize it in Active Directory - the service will not start on a domain controller or member server without authorization.

I'm really suprised you are not on DHCP already, it makes managing and troubleshooting much easier.

But the ZoneAlarm also has a setting to disable / enable the wireless DHCP server. Does anyone know if the DHCP server for the wireless should be enabled?

Hi southernlady,

First, you should check out the man pages for dhcp, and dhclient.

Then try the following:
Find the option under the "System Settings" menu -> "network"
Run the gui client, system-config-network and then edit the network device to change from manual IP settings to dhcp.

I assume a reboot is required after the change.

Hope this helps,

I do see a discrepancy in the IP address:


The 255's mark which portion of the IP address is reserved for network routing and which portion is for computers/devices.

Basically, your DHCP server is handing out IP addresses for the 192.168.137.x network, but the Network card of the server is configured to be on the 192.168.2.x network.

Ok, I'm kind of confused by this whole Win2k3 server doing the NAT and DHCP

1) Does Win2k3 need to have 2 NICs if it's only going to do the DHCP and not NAT? (can it even do that?) I know that if Win2k3 does both it will need 2 NICs

2) If Win2k3 does only the DHCP, I still use a router, correct?

3) Should Win2k3 be doing both? (for say a 25-50 workstation office)?

Answer:Can/should Win2k3 Server be the DHCP server without doing the NAT?

DHCP and NAT are totally unrelated to each other.

DHCP is what hands out IP addresses on your LAN.

NAT allows IPs on a private LAN to appear as a single public IP to the outside world. It also has other uses, but that describes it's major use for simple networks.

Generally the NAT is done in the same place that your firewall is running. If you are using ISA on 2003, then the NAT is done there usually and that does require two NICs (one each for outside and inside). In that case the server is doing the function of the router/firewall and you would not need a separate box. I like to use a dedicated router/firewall though and keep those functions off of the server.

You'll hear opinions each way about where to do DHCP. I usually put DHCP on the router/firewall, but there are sometimes reasons to put it on the server. You do not need two NICS just to do DHCP.

Yes, if you put DHCP on the server, you still certainly need a router/firewall.

It's usually pretty easy to do DHCP on the router and then just make sure you setup DNS properly on the server. If you are running a domain, you MUST do the DNS on the server. In DHCP setup on the router, make your local domain controller (the server) the primary DNS with the ISP DNS as the secondary. That ensures you will always have DNS available.

I always set my wifi network adaptor proporties Ipv4 to "obtain an IP address automatically" . Same for the DNS server. My landlord's acess point gives me an IP address but at some point the network adaptor settings gets changed to static IP and when I look at the IPv4 proporties the next time I see static IP with the correct last IP address assigned from the access point filled in to the fields. This isn't supposed to work this way and the problem is that on the next connection to the access point, the AP rejects the log in at it's captive portal password page with these settings. The only way to get a new connection with log in to the AP is for me to go back into the adaptor's proporties of IPv4 and set it back to "obtain an IP address automatically".

My current network setup utilises a dhcp server per household, each household also has a router and thus the dhcp server hands out a dns/default gateway relative to the house....

The problem has arisen as we have a number of houses wirelessly linked; When a client seeks a dhcp server to assign it an ip and what-not it will often pickup on the wrong house and thus will end up surfing using the wrong internet connection and so on and so forth....

Is there a way I may be able to handle this?

Can the devices linking the homes block broadcast or DHCP traffic? That would solve the problem.

On a more basic level, you could go with static IP's for each box.

Question: Server DHCP or No

Right now I have my server connected to a router and the router does the dhcp for me. I am thinking of putting a second nic in the server and using it for dhcp. If I have computers in the house that are not a part of my domain will I still be able to get online with them if they are connected to my switch? I guess to paraphrase myself I am asking can you use a server to route and not have everyone connected to the server in your domain?

Answer:Server DHCP or No

I'm not sure what DHCP has to do with routing... Are you trying to break your network into subnets?

You wouldn't need a second NIC to move DHCP to your server. If you want to move DHCP from your router to your server, just set up a new DHCP scope on the server and that's all that's required. Clients do not have to be part of the domain to get an address from a DHCP server.

My network is fairly redundant with 2 DC's and DFS running for my file shares.... but what happens when a DHCP server goes down? The other morning my UPS had shut my DC(which does my DHCP as well) down due to a power outage, and all the machines starting up weren't assigned an IP, so nothing worked. I wasn't around so another guy called me, we turned the server back on and everything was great.

Now for fun.... what happens if say, my DHCP server went down completely?? I want to make things redundant enough, that if something DOES happen, that the machines will just grab an IP from another server.

Is advanced server the only option? Will running DHCP on both my DC's work well enough? Just having two scopes?? Will they integrate with DNS properly??

Thanks a ton!

Answer:So... DHCP server goes down.... then what?

Two options:

1) Run two different DHCP scopes from your 2 DC servers. Does this help you much though if a power outage will knock out both servers, requiring manual intervention to turn the server back on?

2) Do it the right way - run DHCP from your switches/routers (assuming you have an enterprise grade switch that allows this).

Sharing a single Public (world) IP address with multiple Private (local) IP addresses will require some type of router that supports NAT (Network Address Translation). Running a DHCP server on the router should only add a small amount of local bandwidth usage when a computer first connects to the router and gets assigned its private IP address by the DHCP server. The DHCP server is then out of the picture until another computer comes on line or the DHCP lease time (could be up several days) expires for each computer.

Is the speed bottleneck related to accessing the Internet through the DSL connection or exchanging data between computers (and servers) on the same local network?

I primarily work off of my laptop computer, but occasionally need to use my desktop. The desktop worked fine two weeks ago, but now it always says "limited or no connectivity" and I cannot connect to the internet. It says that its connected, but when I try to renew the IP address to solve my problem, it says "unable to contact your DHCP server". I have no idea how to fix it. My laptop, as well as two other computers in the house work just fine with the wireless network.

Answer:Help with DHCP server!!

Usualyy shutting down all the computers, switching off the router for a few minutes before rebooting it and finally rebooting each computer one at a time will resolve the issue.

I am using Lubuntu,

OK I have two Ethernet adaptors on a stand alone box.

I need eth0 to be a static address.
And then eth1 to be dhcp.

- how would i write that as a script (what would it say ....)
- Where would I put it so it is run everytim on start up? (or how would i set it so the system runs the script on start up?)
- It would have to do it everytime the box boots/reboots.

Thanks for looking

WHat i have so far :

is where the definitions for the eth0/1 are at.

I can set it to:

# eth0 - Static
auto eth0
iface eth0 inet static
netmask 0.0.0.

# eth1 -- DHCP
auto eth0:1
iface eth0:1 inet dhcp

and after this is written in interfaces, I just need to restart it:
sudo /etc/init.d/networking restart

But I need to not have the user have to do this or anything like this and just have it auto do it ...

I am fairly new to this kind of thing and trying to get it to work today ... ideas on how or what to do to make this work Thanks!

Answer:ubuntu/lubuntu setting eth0 (static) and eth1 (dhcp) on start up, every time. (how?)

After you've saved the interfaces file and reloaded the networking service, you shouldn't need a script to set it back to that every time your system is rebooted as no user should have access to modify that (or else why do they have sudo rights?). I take it you know the actual addresses you've put in are all incorrect? If not, do you need help configuring that too?

I have no clue where I need to go with this, I've tried google-ing but have found nothing, I don't exactly know the right terms I need to use either. Basicly, I'm trying to make my backbone LAN Party server PC be the DHCP server and a DNS server and host the Intranet site. I had a guide on setting up a webserver on XP Pro but seem to have lost it somewhere..... all I have setup is the IIS needed to run it, and can only view the default pages from the lan server machine - localhost and the ip - I can't access it from any other pc on the lan......

I was told there was some program that does this automaticly have not found it.

Planing on being:
*Backbone LAN Server - demos / patches / files

Answer:Trying to seutp DHCP + DNS server on XP Pro

I am fairly certain that XP pro cannot be a DHCP server by default. Maybe by installing something, but I would think not there either. You need a server class OS, or some linux distro if you don't want to shell out that kind of cash.

Actually, heres a DHCP program for windows

If your PC is set to obtain an IP address automatically at boot up then it uses a DHCP broadcast system, this system sends a DHCP request via the network software through the network card and through the network cable out on to the network, if a DHCP server is available then it will reply and your PC will be given an IP address by the DHCP server,

DHCP servers can be a router, a PC running Internet Connection Sharing, or a PC running a DHCP client (such as on windows 2003 server).

If your PC cant find an DHCP server and you have it plugged into a DHCP server then either the cable is wrong or faulty, or the DHCP server is not seeing the PC.

Please post back saying what exactly you are trying to achieve.

I am having a problem connecting to the internet. My ip addresses were wiped out and windows assisgned its own. When I try to repair my broadband lan I get an error that says can't repair or can't clear arp cache.
I've deleted the winsock and winsock2 files and tried again and still can't get it to assign the correct ip addresses. My os is xp and it's already set up to automactically assign. I've tried several times to do an ipconfig /release and /renew and it isn't working. Time Warner cable dosen't know what they're doing and can't help fix it either!! Please help!!! :cry

Answer:cannot contact dhcp server

Unless you changed something that you think caused the problem the problems seems to be the fault of your ISP. The DHCP server isn't in your house so you really can't do much about that.

I have reviewed the posts on DHCP but have had no luck in resolving my problem.
I have An NT 4 server as PDC running DHCP (The service is running)
2 NIC's in the server with static IP's and
Scope with a rang >

I did not config any other options
No Routers, WINS or DNS Just trying to get DHCP working first

Static IP on WIN98 clients work but when I select DHCP the client receives the "No Domain server found...and I get the windows default address.

As a test I have an ISDN box that acts as a DHCP when I hook it up to the network the clients do receive an IP from it. This box will not be on the network so I need to get DHCP running on the server.

Looking through the other posts, I can not find any problems with the setup or config.

I have a DHCP server running on Debian woody of linux. I had a problem with my MS2k Terminal Servers taking up 8+ dynamic IPs each from my DHCP range (even though I shut down the DHCP client service on them and they are single NIC static IP machines)

When I first set up the Linux DHCP server they had leases out. I since set them up as reserved IPs in the DHCP setup and it is still showing the TS in the leases file, but their end dates are 5/26. Do they just not clean out of the lease file until they are claimed by another machine or what? Anyone know for sure if I can just remove them safely from the leases file to clean it up or anything?


Answer:DHCP server on Linux

dhcpd on linux is one of those nice servers that you don't have to touch to keep running correctly.

Leave the lease file alone, it'll figure itself out. When it has to allocate them, it won't have any problems doing so.

We have a Local Area Network at work and on this network we have a VM Server with Windows 2003 Server R2 that we plan on using for Active Directory and this server also has DHCP and DNS Server configured on it. is the Server IP. NAT is not configured on the server but is configured on the router.
From this Network I have my own private address range
which connects to my NAT Router. I am able to get an ip address of from the DHCP Server for my XP Client

interface vlan10
ip address
ip nat outside
no shutdown

Next I setup a second interface on my NAT Router.
Interface Vlan 300
ip address
ip nat inside
ip helper address
no shutdown

I set up the range on the same DHCP Server
When I connect my Windows XP Client to Interface Vlan 300 I am unable to get a DHCP address on this client but on the server it says that it received an ip address.
DHCP Server address
ip address

DHCP Server Setup
Vlan 300
ip range -
DHCP Options:
003 Router
006 DNS Server
015 DNS Domain Name
046 WINS/NBT Node Type 0x8

Any Ideas on how to fix this so I can get a DHCP address on Interface Vlan 300 I am assuming it is a configuration issue.

Answer:DHCP Server behind a NAT Router

it's actually a routing issue; if you can add proper routing from the router to the server,
it will all work.

HOWEVER, it would be far easier to just place all systems in the same subnet.

I'm studying basic networking, and I understand what a DNS server does, and I also understand what a DHCP server does. I only understand them in terms of my cable internet provider, though. In terms of commercial networking, I don't understand why a business or company would need an internal DNS or DHCP server. Why do they? Thanks..

Answer:DNS/DHCP server question

A lot of reasons.

If you have 500 different PCs in your company, will you run around to each one and assign them all static IPs?

And DNS is needed to locate internal resources. Your ISP's DNS won't know what IP "Downstairs_HP_LJ" printer is.

Hello everyone!

I'm new to this site and I've searched for a topic related to my problem, but couldn't find anything.

I had Norton Internet Security 2005 installed on my computer, but when I added a new hardware item to it, I had to uninstall NIS and re-install it because it wouldn't work. After rebooting, I couldn't establish an intranet connection that did work on the comp before. I managed to find out that there is no default gateway on the LAN, because "no DHCP server was found". To be honest, I don't even know what this exactly means, but anyway. Here's what I tried so far, and didn't work:

1. Restore the default winsock settings, with the netsh winsock reset catalog command and with downloaded winsockfix programs too.

2. Try to renew the IP-address by right-clicking on the LAN settings.

3. Reset TCP/IP stack to installation defaults, with the netsh int ip reset reset.log command.

I've got Windows XP Sp2 and a D-Link DSL-360T modem/router, with ethernet.

I would appreciate any help, but please write it in an "advice for dummies" way, I'm quite a newbie with technical issues. Thanks in advance for your help!

Does anyone know of a free DHCP server for Windows XP? I have an extra box here running XP Pro and I'd like to run DHCP on it so I can hand out static IP addressing. My router can't do it, and I don't feel like loading Win2k server either. I've been hunting for weeks and I haven't been able to find one.

Answer:Windows XP DHCP Server

DHCP is kinda the opposite of static addressing. Anyway, this might help. I've never used it though, so I don't know how good it is.

so i want to move my dns and dhcp to a server (sbs2011). i am currently using a netgear 3700. i am a little confused on how to set this up. i know to turn off dhcp on the router. Here are my questions

will the server give out a dns address?

do i even need to router, or could i just use a switch?

if anyone has any insight i would greatly appreciated it. and if you know of a good guide somewhere please send a link.

Answer:adding a server for dns and dhcp

You will likely still need to NAT, so for that youll require a router on your network. You can have that server do dhcp and either hand out your isp's dns servers or have it do dns lookups and hand its own adress out to your clients.

If you type configure /all at the command line it will give you lots of information on your network, including whether DHCP is in use or not.If you have an IP address in the range 169.254.x.x it means that for some reason the DHCP server is not available. and you need to set a manual IP address.Stuart
