unable to connect to DHCP server

Q: unable to connect to DHCP server

I got a new desktop loaded with Microsoft Vista.

When I couldn't connect to my router (at home) I tried ipconfig /renew /reliease commands and got the following message:

"Unable to contact your DHCP server".

I brought my PC to work and it connected fine to the network there.

At home I use the modem/router provided by Verizon (FIOS). I tried several ethernet cables - so I am pretty sure it is not the cable.

BTW, other pc's at home are connected to the router, so the router is OK.

Any help is appreciated.

Preferred Solution: unable to connect to DHCP server

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: unable to connect to DHCP server

Check the setting on your Router which served as your DHCP as well. Make sure that the Router provides enough IP addresses for your home network.

To Whom This May Concern:

I tried installing SP1 on a desktop Vista, with other windows updates, and my internet stopped working. My Xbox and another computer (XP SP2) work fine and haven't noticed a difference.

I've contacted my manufacturer, and they said uninstall everything. I did. There is one Windows Update and one Microsoft .NET Framework 3.5 SP1 that it won't let me uninstall. I've contacted my ISP and they said there's a problem between my modem and hub, but if that's the case, my other computers wouldn't be working either.

I've contacted Microsoft, several people, and after many procedures, concluded that I need a restore disk and set it back to factory settings. This is an absolute last resort.

Here are my specs:
Vista Home Premium
Desktop
AVG 8.5
Comodo Firewall
XtremeGamer SoundCard
I don't know what else is important since the computer has worked for a year before attempting SP1

Here's what I've tried:
-ipconfig release, renew
-enable and disable dhcp broadcast flag via regedit
-exchanging cables, all cables work with other computers
-netsh resets
-clean startup tray
-closing viruscan and firewall, leaving one open, all possible combinations thereof
-power cycling the modem and hub

Hi!

My daughter got a virus on her laptop and after getting rid of it (I think all the way, it's hard to tell until I can update the anti-virus software) I can no longer connect her laptop to the internet.

I have had a problem in the past with having to reboot the server and all the computers in order for the computers (all of them in the house) to register new ip addresses. Normally, if I have one computer that refuses to connect even after a reboot of the entire system I can connect it thru LAN and it, bang, fixes itself. However, this time it is not working.

Not only will her wireless not connect but neither will the LAN. I have opened the cmd prompt and done an ipconfig/release and ipconfig/renew. Every time I do this I get the message:

"An error occurred while renewing interface Wireless Connection : unable to contact your DHCP server. Request has timed out."

I tried the "netsh int ip reset resetlog.txt" and it seemed to work fine.

I also tried the "netsh winsock reset" and it seemed to work fine as well.

I rebooted each time I attempted a fix. Still I am unable to connect to the internet. It says it is connecting locally, but will not connect to the actual internet. When I use the repair option it gives me the same messages over and over that do not work. It always leads back to the IP address.

Here are the specs on her computer and as much information as I can think of. Please let me know what else I can try to get her compu... Read more

I just got Cox cable and it hasn't been working right.

I have a netgear WG602 wireless access point. I can connect to it but it has limited or no connectivity. Repairing the connection doesn't work and doesn't give me an IP.

I connected the ethernet cable directly to my laptop and it didn't work at all. I called them and it worked by directly connecting, but the wireless still didn't work.

Then I messed with wireless settings to try to connect, and I finally got online but my ip is 70.x.x.x, the apparent IP for all Cox subscribers.

But I got that 70.x.x.x through my router instead of a 192.x.x.x so I have no idea why it's doing that. It's really weird and I still can't get a dynamic IP.

Thanks for the help.

A:Network could not connect to DHCP server

Nothing really comes to mind, but if you're using Window's Wireless Zero Configuration maybe you need to reconfigure your wireless connection; especially if your network is protected with encryption.

I use the utilities from my wireless cards' manufacturers to connect to my WPA protectecd network and had no trouble today after the same reboot (two notebooks). Well, same reboot if you're talking about the critical update released yesterday.

- Uninstall and Reinstall mobo network driver. (MOBO - http://www.newegg.com/Product/Produc...82E16813130187)
- Updating the network driver via flash drive and a working computer.
- Winsock and netsh int ip fix.
- Returned mobo and replaced with same model.
- Removed HDD, connected to a working PC, installed winxp, everything worked. Took out the HDD, installed into non-working pc. Same issue as before.

Please help.
 

A:Unable to contact your dhcp server. (I've tried everything!)

It would be helpful if you could tell us how you connect to the Internet. Are you on cable, DSL, dialup? We also need to know who your ISP is, what your brand and model of modem are, etc. Without more information, there isn't any way to resolve your problem.

I just acquired two Gateway e6000 Pentium 4 2.4 Ghz XP PRO machines from work,(put out to pasture). They were setup to login to our domain at work and then after authentication you could access the internet. They were setup to receive an IP address from our domain controller and DNS was controlled by a local server. After bringing them home, I removed them from the domain and created a workgroup. I also set all TCP/IP properties to authenticate automatically and removed all instances for DNS. My current internet connection at home is a Westell Ethernet ADSL Modem C90-36R516 with a Cat5 cable going directly to the NIC. My existing home computer powers up and receives an IP address from the Westell without a problem but when I try attaching either of the Gateways, I get the error listed above. I have spent many hours troubleshooting this problem. I have tried the release/renew command, clearing the IP stack with netsh, checking security policy, clearing IP filtering, plus many, many other things. I was able to establish a connection and get on the internet with a Gateway but only after I gave the new Gateway a fixed IP address, default gateway and DNS entries that matched the current settings of my home computer. Correct me if I am wrong but I think I am issued a different IP by my Westell modem/router every time I boot up my computer. Or does this IP come from my ISP? And if the IP changes with every login, the Gateways will then not be able to login after a shutdown. Any idea... Read more

A:Unable to contact your DHCP server

Hi surffishermanca, and welcome to TSG.

Some ISPs (like SBC/ATT) configure the DHCP server on the modem to only give out a limit of one IP address, unless you sign up for some type of home networking plan. Try power cycling the modem when you switch computers.

EDIT: Thank you very much for all the details. Most people here would rather sift through bits of extra data than not having enough.

-Reset TCP/IP with the netsh command and tried the netsh dump
-Confirmed I do not have a network bridge running
-disabled my 3rd party firewall
-reset my modem and router
-checked cables
-deleted & re-installed the NIC
-Start >> run >> services.msc >> DHCP client >>go to "Dependencies" and
checked for the following items:

Hi,

My laptop is SAMSUNG RC510 model. It has Windows 7 64 bit. To connect to internet i have to plugin the LAN Cable to my system and it has to automatically get one IP from DHCP server. Then i have to open a website and login to connect to internet.

But when i plug in the cable, it does a try to connect to the DHCP server to get one IP. But does a timeout and set one default IP with 169.x.x.x.

Same when i inserted to a different laptop it had no issues.

Things i have tried are:
* Doing a release and trying to renew the IP from command prompt
* Disabling kaspersky Antivirus.
* Uninstalling the antivirus.
* Disabling all rules from Windows Firewall
* Uninstalled Virtual Box software to make sure other network stuff not creating problem
* Uninstalled and installed the driver several times
* Disabled and enabled the connecting several times
* Plugged out and in the cable several times
* DHCP and DNS client are running and set to automatic

But still it cannot make my laptop's LAN to get one IP from the DHCP server of the connection.

I cannot set a static IP as it has to work in DHCP.

Please help me out.

Maybe only the one computer is allowed to connect and you have to call the provider to "reset" the connection or to register another computer to allow it to connect.

netsh windows reset catalog

Doesn't fix my problem.

3. Another try

netsh interface ipv4 show inter

then: netsh interface ipv4 set interface 20 dadtransmits=0 store=persistent
then: disable startup type for service "DHCP client", stop the service, unplug Ethernet cable

then: startup type = automatic for service "DHCP client", restart the service, plug Ethernet cable

I've been trying (in vain) to connect a USB Wireless device to be able to use it off my wireless network. I have (2) other laptops and (1) other desktop connecting to the router with no issues.

For some reason, this old desktop keeps installing an Ethernet device (probably on the MB) and is automatically Configuring the IP address to that instead of the USB wireless device.

I've tried uninstalling the Ethernet device but it comes right back after I do a reboot. Even when I disable it, I still can not connect with my Wireless device.

A:unable to contact DHCP server

Try This

Disable the XP firewall and try again. If it works, set it back up but as part of a LAN.
From the command prompt, ping 127.0.0.1 and see if you get OKs back. That means your network adapter is probably Ok.
Next, run the Wireless Network Setup and see if it recognizes the network adapter and can detect your LAN. Unless you've changed your WEP/WPA passwords recently this should work.
Run a virus scan and see if you picked up a bug.

Let me know how it goes

I would appreciate any help you can offer here. I have a desktop computer directly connected to a cable modem. It was working perfectly fine the other day (it was connected to Comcast). Since then I have moved, and tried to connect it to another cable modem (this time it's a Time Warner modem). I keep getting the "limited connectivity" error and when I try to release and renew the IP address, I get the error "unable to contact your DHCP server. Request has timed out." I hooked it to my laptop and it works perfectly fine, so I know it's the desktop. Ipconfig of the desktop reveals a 169.254.xxx IP address. I have a Broadcom 440x 10/100 Integrated Controller. I have no network bridge. I have tried the following:

Updated the driver to the most recent
checked the DHCP settings in Services
uninstalled my McAfee virus scanner/firewall
reinstalled TCP/IP from windows\inf and rebooted and release and renew several times
reset the resetlog.txt and rebooted and release and renew several times
Is it possible that Comcast had it configured a specific way and now it won't work with the Time Warner cable modem? Is there a way to completely reset the settings? Is there a setting a can check or change?
Thank you.

I just replaced my XP desktop with a W7 laptop. I have had constant network issues. I have a home network with a Linksys WRT54G running DD-WRT. My old XP computer worked fine as do another laptop running XP and three other networked devices: Tivo (wireless), WD TV Live Hub (wireless), WD NAS (wired). The W7 laptop takes a long time to connect, first as a "Public Network" without internet capability. Then about one minute later (sometimes longer) as a "Home Network" without internet. Then about one minute later (sometimes never) with internet. After a few hours usage, the connection goes away, becoming a "Public Network". I cannot even access the router configuration page. The only way to get connected again is to physically unplug my router. My router is set up for DHCP and all devices, including the new W7 laptop, are configured to automatically obtain IP addresses from the router's DHCP server. I noticed that my IP address, in ipconfig /all, is "192.168.1.130(Preferred)." I haven't seen a good explanation yet for the "(Preferred)" part of it. When I try to renew the IP address, the error message is "unable to contact your DHCP server." In the router settings, I have tried to assign a "static lease", something I did with my XP desktop, but the IP address never takes. I have run a Microsoft fix for TCP/IP stack.

Hello all! Thanks for reading this!

I am having some troubles with my wireless connection. First of all, it is not the router because another laptop running Mac OSX can connect to the internet just fine. I have tried renewing the connection, doing all the netsh things and still no luck. Here are my specs when I do an ipconfig/all.

DHCP is enabled
Autoconfig is enabled
IP Address is 169.254.133.75
Subnet Mask 255.255.0.0
Default Gateway 169.254.133.75

Please help me! If there is anything else you need to know just let me know.
 

A:Unable to conect to DHCP server

Hi

it sounds like the wireless connection isnt coming into play at all, the address you are getting is the one windows assigns when it cant find any DHCP servers and is set by the OS DHCP server.

are you using the windows software to connect to your wifi or are you using the cards own software..?

A friend of mine gave me his laptop to reinstall him windows XP on hp compaq nx6310 (clean install). after i installed windows i went to http://h20000.www2.hp.com/bizsuppor...sId=1839143&swLang=8&taskId=135&swEnvOID=1093 and installed all drivers under Networking section just so i can get internet on it. well that didnt go as planned. i mean i installed all the drivers but i'm getting Limited or No connectivity conection on Local Area Network 5 (connecting it with cable cos im pretty sure this laptop has no wireless oO).
when i try cmd -> ipconfig im getting 169.254.x.x and "unable to contact your dhcp server" message... Would really appreciate if you could help.

Thanks

EDIT: also when i unplug the cable from the laptop and plug it in desktop computer I get Local Area Network connect and internet is working...
EDIT2: could it be that i've installed wireless drivers on this laptopt (that doesnt have wifi) and that they r now interfering ?

I have a Dell 570 Inspiron desktop running win7 home premium w/ a 64 bit OS. I have Frontier dsl with a Westell 327W modem and a netgear router. Two desktops are connected to the internet...one through the modem and the Dell 570 through the router. I also run laptops through the router w/no problem. This morning the dsl went down, and when it came back up, the Dell 570 would not connect. i tried Diagnosing Connection Problems, and I'm told to turn off the modem/router (which I have done a gazillion times). When I look at Network Connections in the Control Panel, It tells me I have an unidentified network and can't connect. I read through some forums earlier, and found that releasing and renewing ipconfig often corrects the problem, and that's when I got the message that 'An error occurred while nenewing. Local Area Connection unable to contact DHCP server.' This set up has worked for the past year and a half. I looked at the network adapter, and it says it's working properly. I changed the cables going to the machines, and they both work on this computer. The only change made to the computer was to install McAfee security center through AOL yesterday, but the set up worked all yesterday and last night. I am not very techie...i can make some software sing, but when it comes to hardware and networking issues, I'm not too bright. Any help you can provide would be much appreciated. Problems like this make me crazy.
 

A:Unable to contact DHCP Server

After uninstalling McAfee run the McAfee Removal Tool.

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.

If necessary use a text file and removable media to copy the results to a computer with internet access.

I was working on a XP SP2 computer yesterday and was unable to establish a valid IP address. I was able to get a valid IP address with another XP computer so I know it's not the service itself but the computer. I tried running winsock fix, removed Norton Internet Security to make sure it wasn't creating any conflicts, installed a Usb-to-Ethernet adapter--I even restored the computer to a month prior to no avail. The weird thing is, I'm able to get the initial local IP of the cable modem itself which is a good sign but when it tries to release the local IP for one assigned by the DHCP server, I get all 0's or a 169 IP. Any ideas on what is happening?

Hi Guys,

I have been experiencing some irritating problems with my internet and creating a hosted network for my mobile devices. creating a hosted network was easy and has worked for quite some time until this weekend. Doing some quick google searches almost all the results said I should release then renew my ipconfig, and this is where all the real problems started. It won't renew and from there my problems keep coming.

My connection is provided by my university so there is no way for me to quickly reset the modem.

Well, let's do the official stack repair, since you didn't say exactly what you did.

TCP/IP stack repair options for use with Vista or Windows 7.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.


Next, if that doesn't do it, I'd suggest a run with SFC since it's saying a file isn't found.

- try safemode with networking (sometimes wireless does not work with safemode )
as the PC starts keep tapping F8 - a menu appears - choose

have you changed the cable at all ?

Hey i got similar problem.I have dell inspiron 1501 (Vista32) and routher Linksys WRt54G.
I keep getting "local only" and "limited conectivity".I realized that the problem is in my pc because the other pc's connect to the access point without problems.I tested the following:

plugged directly to the modem=no success
plugged to the wireless routher=no success

When i looked into the info from ipconfig command i get this ip:
autconfigured ipv4 169.254.15.197

Due to that i entered ip manually something like:
192.168.1.2
255.255.255.0 and default getaway 192.168.1.1
then tried with disabled ipv6
Still nothing.Then tried netsh int test reset ip and netsh winsock reset catalog without success!
The i upgraded my wireless card drivers and routher firmware just in case,reseted the routher to factory defaults and still nothing! I really dont know what could be the reason for that.Since i bought the laptop 1,6 year ago didnt had any problems.
I think everything started after i uninstaled Norton Internet Security and using Norton cleaning utility! I instaled Eset smart security and i started to get blue screen of dead! I wasnt able to log on to windows.After uninstalation i was unable to connect to internet.

Hi -
I have an older IBM Thinkpad (365X) with Win95B. I have a Xircom Ethernet/56K Modem PCMCIA card, which I know works, since I can use it in other machines that I have.

I have DSL with a netgear router that has a DHCP server, which I also know works, since I'm using it to send this message.

I have reinstalled the adapter, all of the protocols, the client software, and the physical card in every way I can imagine, and cannot seem to get the machine to recognize the network. I checked the MS support site, and downloaded the Winsock2 patch. Didn't help. Still getting message about not being able to obain an IP address from the DHCP server. Most frustrating.

When I ping my own machine, I get an response with no lost packets. When I ping any of the 3 other machines on my local network I get a "request timed out" response.

If I hard code the IP address into the machine, I still cannot see any of the other machines.

I'm about ready to give up, so if anyone has any other ideas, please let me know.

Thanks

Since you said this was dial up did you check all of the Network adapter settings to make sure its not disabled anywhere?

Hi all, got back from the beach and was greeted with internet troubles.

My desktop is the problem, running Windows XP SP2 and I have already tried a number of things:

Running ipconfig gives me a 169.254.***.** address, which I understand is a private IP or something.

Clicking "repair" on the right click drop down box on my local area connection gives me: "Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address."

ipconfig /release and ipconfig /renew gives me the following error:
"An error occurred while renewing interface Local Area Connection 4 : unable to contact your DHCP server. Request has timed out."

I have 2 other desktops and 2 laptops running on the exact same router, all are working like a charm. It appears to be something on the software side of my problematic desktop. I tried setting my IP manually by going to properties under Local Area Connection, then TCI/IP properties, but I don't know what to put as my DNS addresses. When I set my IP to what I know it SHOULD be and my default gateway to 192.168.0.1, my connection tells me everything is all right, but alas, no internet.

Any suggestions? And sorry if this is a repost, but the solutions for other people didn't work for me.

A:Unable to contact your DHCP server. Request timed out.

"Unable to contact your DHCP server" means that no Dhcp server responded to a request for an IP configuration. To begin troubleshooting you need to determine if there is an enabled Dhcp server on the network and the components of the network between the Dhcp server and the computer.

The connect the computer to the Dhcp server with the shortest possible path. Usually this means an ethernet cable between router and computer. If that works then add components one by one until you determine where the blockage/disconnect/defect is.

I tried opening the cmd window and putting in ipconfig/renew, but it says that there is an error and it is anable to contact the DHCP Server and the request has timed out. The internet everywhere else works just fine however (I am at work right now and it works, and I went to an internet cafe and used it there without a problem as well.

Does anybody have any ideas of how to fix this problem? I would really appreciate it!
 

A:Cannot renew IP Address, Unable to contact DHCP Server

1. Check the wifi /router end of the connection is configured to be a DHCP server
2. Beyond that there can be many variables. I think you're best approach:
=== > Backup the wifi / router settngs (most devices allow you to backup their config to your hard drive. Check the user manual)
===> Remove all the restrictions that were added via the config (e.g encryption, MAC address screening, etc.
3. Verify you and neighbors computer all connect and work when no restrictions.
4. Add back restrictions one-at-a-time and retest the computers (yours and neighbors) until they all work and all restrictions have been applied
