DHCP client tries to aquire an IP for not connected network cards

Q: DHCP client tries to aquire an IP for not connected network cards

Hello,

I have a problem with a Windows 7 64 bits. After power on, the DHCP client tries to acquire an IP for all the network cards, even those that are not connected.
I can see in the event logs that after 2 minutes from the startup, I get one message for each interface





Quote:
>
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0xMAC_ADDRESS. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."


I have an Astaro VPN client that manifests itself as a network card and when I start it up (manually) it fails to receive an IP from the DHCP server. I believe it is related with this general DHCP problem because if I start it up within two minutes from power on (before I get the message in the event log), then it works.

Any idea how to debug this problem?
I had a Dell connection manager which I uninstalled (thinking it will solve the problem), maybe this one left some bad traces. Any idea how to find and remove them?
In general, how would one know all the programs that are dealing/interfering with the network connections and dhcp settings?

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.)

hi i've been at trying to fix this since 8am and am having no luck

i reformatted my laptop (toshiba sat l35, updated to SP3) this morning, and installed the drivers etc etc..

i can NOT for the life of me get it to connect without the cable directly plugged into it. it was running fine off of the wireless connection before, and idk what i did to it..

well, its saying i am not acquiring and IP address, i'm sending out packets, but not receiving any.. and idk if it matters or not, trying to run off of road runner + a linksys router.

renewing and releases the IP doesn't work. resetting the router doesn't help. trying to repair the connection doesn't go threw all the way because it says i have no IP address..

any help would be MUCH appreciated! thanks

My Buffalo AirStation Draft-N WZR2-G300N does not aquire the IP Address from DHCP server. The status on the config page shows "Contacting".
I tried the buttons "Release" and "renew" but of no use.
I am now using it in Access Point mode, it works fine. Earlier i was using it with a static IP configuration, even here its working fine.
One more problem is i can't get to the router's config page in Access Point mode. I tried both 192.168.11.1 and 192.168.11.100!!

Thanks in advance for the help.

I have 3 network cards in my Windows 8.1 computer.   Each is attached to a different network.   I have assigned a static IP address to network card 1 which is on the internal LAN segment.   I want the other 2 network cards,
which are on different networks to run in promiscuous mode (IE.  No IP Assigned) so that I can sniff traffic.   There are no DHCP servers on those 2 other networks but there is one on the LAN which card #1 is plugged into.

My problem is that the 2 other network cards are getting IP addresses from the DHCP server on the card #1 network.   How is that possible?   If I disconnect card 1 from the network, the other 2 cards don't get an IP address.  
If I connect card #1 again, the other 2 cards get a DHCP assigned address.   So how to I stop network card #1 from forwarding DHCP traffic to cards #2 and #3?   Anyone know?

Thanks.

Dear User ,

i have one question that i have connected my computer to two different internet connections. one through lan and other with wifi. for the lan default gateway is 192.168.1.1 and gateway for wifi is 192.168.3.1. for example i am downloading any file where i can know which connection is downloading this file ???

Best Regards

A:if you have 2 network cards and both connected to different ISP.

The netstat command, from a command line, can help here. It show a brief report of all active connections. Look at the estabilished ones, and then look at the local IP column, that will tell from which network card the connection was done, from which you can get what ISP is actually serving it.
The destination IP can be useful to distinguish which network activity are you looking at.

I got help on the security forums and most problems seemed to have been fixed, except now my internet won't work at all. We have cable connection with no router, just straight from the wall to the modem to the pc, at first i thought it might be the ethernet cable so i replaced it, but that didnt help/ It doesnt seem to be the modem, and repairing wont work. Whenever it gets to the aquiring ip address stage it just stops and tells me it cant renew my ip and to contact the person who manges m network, then im stuck with a connection with limited or no connectivity.

Hi its me again..... I have set up the ecryption for the wireless router and all was going great. The lap top worked great. Now when I try to connect to my network it says I cant aquire an ip address What have I done???
 

A:Solved: cant aquire network ip address

I have also done this:You want and need to encrypt your wireless signal. Login to your router via your browser, go to the wireless section and enable WPA (or WPA2 if supported by router and laptop) encryption. Use a passphrase of 20+ letters and numbers. You will then need to give the same passphrase the next time you connect the laptop.
It was working .Do I have to make any changes to the laptop. I clicked repair to renew the ip address and it said it couldnt .

Hi,
I have an odd problem that I can't figure out. I recently had a malware/virus issue that was resolved. However, after the issue was resolved, it was discovered that I was missing numerous Windows XP critical updates. after visiting the update site and rebooting I now have an issue with my wireless internet. I still have an internet connection, however I have a poor signal quality and the tray icon "wireless network connection status" is always present trying to "acquire a network address". Please Note, this an HP laptop with windows XP Sp3. It uses the HP wireless network assistant to set up the internet connection. however I never had this problem even when I was infected with virus/malware. I also never had this happen anywhere that my spouse went, it always connected without any problems. I wasn't until I went to windows update that this problem happened. Any suggestions would be greatly appreciated.

A:Unable to aquire a network address

Some things to try, do you have a router or modem, reset them to see if they are stuck.

I am assuming you are not using a dial up? In Internet Explorer go to Tools>Internet Options? Click the Conections tab, and then the LAN Settings Button, make sure 'detect settings automatically' is checked.

See if that helps, do you have any signs of malware infection?

Start by disabling all encryption and MAC filtering on the router and get it connected that way. Also, remove all stored wireless profiles on the laptop and search for a new network. Finally, when you get it connected with no encryption, enable WPA2 again.

I've searched for other threads addressing this problem, but haven't found anything quite like my problem.

I have a Dell Latitude D600 laptop with XP Pro Service Pack 2 and a Dell TrueMobile Wireless Card. I can connect fine to my home wireless network and have no problems.

However, whenever I try to connect to another network, wired or wireless, my computer will connect, acquire a network address that I think is a real one, work for about a minute and then announce that I have limited connectivity and acquire a new address. The networks I'm trying to connect to don't require a password.

For instance, I'm currently in my office (I'm a grad student). We have an ethernet cables in the office. My officemate is able to plug her computer in and get a connection with no problem, but I'm posting this message in my brief one minute of connectivity.

For now, I've disabled my firewall and my wireless card (since there's a wireless network with a very weak signal the computer tries to connect to if available).

I ran ipconfig/all but can't my computer to let me copy the results and paste them here.

Any advice?

Thanks!

For awhile every now and then my computer decides it needs to 'acquire network address' on booting up. It never does succeed unless prompted by my going into Wireless Connections and pressing 'repair'. Yet my connection to the Internet is not impeded even while the little yellow ball hovers round mini monitor in the taskbar. It is hovering now as this thread is written.
ipconfig reveals Connection Specific DNS suffix is missing, but the IP Address is there. My ZyXel 7087 router shows a fixed W/LAN/WPS and DSL light, but the Internet light is continually flickering, regardless of whether the computer is on.
The TCP/IP is set to,'Obtain an IP address automatically' and 'Obtain DNS server address automatically'. Advanced TCP/IP Settings shows DHCP Enabled. DNS tab - DNS server addresses box is blank 'Append primary and connection specific DNS suffixes' is dotted and 'Append parent suffixes of the primary suffix' is ticked. 'Append these DNS suffixes (in order)' is unchecked. WINS addresses box is blank. 'Enable LMHOSTS lookup' is ticked. NetBIOS setting - Default (checked) - Use NetBIOS setting from the DHCP server. If static IP address is used or the DHCP server does not provide NetBIOS setting enable NetBIOS over TCP/IP. Enable & Disable NetBIOS over TCP/IP unchecked. Can anyone resolve this issue. PS While reading the WNC status the computer has found the Network address, but all above remains true.

Hello. I saw a topic similar to this one, but it was for a different type of computer.
My laptop is a Dell Latitude D830 with Windows XP Home Edition. I just recently had to reinstall XP due to a virus. When I was finished installing it, there were no options for wireless internet available, even though there had been before. I took the computer to the IT guys at my University, and they installed some drivers, so everything is almost back to normal. I am able to access the internet at school, but at home, I only get messages like "Internet Explorer cannot display the webpage" and "This address is invalid." It also says "Limited or no connectivity. This problem occured because the network did not assign a network address to the computer." My router is a Linksys router, and no one else in the house is having trouble with connectivity. How can I fix my wireless internet?

One of the services that runs automatically in my Win2K system is DHCP Client.Codestuff Starter says of this that it "manages network configuration by registering and updating IP addresses and DNS names." It certainly seems to be be necessary as when I disabled it to test it I found that I could no longer connect to the Internet.But on checking the Bleepingcomputer Startup database I found the following:Name Filename Status DescriptionDHCP Client dhcpclient.exe XAdded by the W32/Codbot-AG worm. When started, this infection connects to a remote IRC server where it waits for commands to execute.I then ran a search and there is no dhcpclient.exe file in my computer so it would seem there is no problem.Or is there?

A:Dhcp Client

DHCP Client is legitimate. If you statically assign a specific ip address to your computer you can disable it. If on the other hand, a router or server provides the ip address to your computer when you start it, then you need to keep this running.

Hi! I have had to reboot my computer recently due to possible infection and whilst before my wireless connection was absoluley fine now I am having problems. I have connected the adaptor as instructed by Negear and it can find the network, but will not allow me to aquire a network address. I have two laptops (and i-phones) on the network and all these appear to work OK so I assume that the router and modem are working fine and the problem lies with the settings on my computer. When I go onto properties of the connection I find the IP/TP protocol and this is set up to get IP address automatically. When I input a manual IP address it says that it is connected but I cannot get onto the internet. I am totally confused. I managed to get it set up before but don't know where to go next.

I need help to either repair or replace my malfunctioning DHCP (Dynamic Host Configuration Protocol) Client. When it's running, I cannot shut down my computer by simply going to START=>TURN OFF COMPUTER. When I do this, the computer hangs. To get around it, I have to CTRL/ALT/DEL to get Windows Task Manager. From there if I log-off the user, I can shut down the computer.

Also, since this problem came up, I cannot access the Windows Update pages. When I attempt to do this, the computer hangs. Again, I have to open up Windows Task Manager and use "End Task" under the "Application" tab to manually shut down Internet Explorer.

The problem started in December when I downloaded Service Pack 2 for Windows XP. Later that same day, I decided to purchase and download Norton Internet Security 2005 to update my 2003 versions of Norton AntiVirus and Norton Explorer. The update failed to install properly. It was after that that I discovered the shut down and Windows Update problems.

I have since removed all of my Symantec / Norton products to eliminate them as potential problems. Initially I thought it was an operating system problem, so I initially posted a thread to the "Windows NT/2000/XP" section of Tech Support Guy Forums.

Hi.

Recently we bought two Compaq computers running Windows XP Home; we have cable internet and after the computer is left alone for a few hours, the internet just dies.

I have also found that if I restart the DHCP Client Service, then the internet boots up immediately. Is there a resaon for the DHCP timeout in Win XP Home?

Thanks a lot.
 

A:DHCP Client Service

every time that the internet dies, do you get a new IP address? if you do, it might be on the ISP side that is doing it..

also, if your running power managment, it might be set to turn off the NIC. goto the properties of your NIC in the Device manager, and check The Power Managment tab.. and you can check out the Power Options in the Control Panel..

hope this helps

I've tried sfc /scannow and came up clean.

Added permissions to registry keys for dhcp and tcpip.

Originally I posted in networking section because I could not access internet and discovered DHCP client was 'missing or marked for deletion'. I did have a recent barrage of virus attacks a month or so ago and it was suggested I post this here. I have attached all data as instructed

Hello,

I tried ComboFix, not in optimal conditions and without reading some recommendations before... thinking there would be some warnings and steps where cancels if it is too risky. Bad game. Moreover, I was/am not infected.

So... I retrieved the control of my machine, with damages in services. I lost the "PolicyAgent" service, which I disabled because it is created and stopped very very quickly, and so services.exe saturates the memory.
But firstable I need to fix the DHCP Client, which always takes 100% CPU and doesn't do its job very well. Here are 2 event logs, activated for 1-2s, I'm not able to understand what it is about :
http://www.partage-facile.com/20DT89L53Z/dhcp_client.evtx.html
http://www.partage-facile.com/P0J2BZVGAV/dhcpv6_client.evtx.html
I don't know if you will see it in English, tell me if I must retry.

Hoping you can help me !

Edit : of course I'm on Windows 7 (x64).

I have a Dell laptop running under Vista. It has been fine (had for about 2 years) but suddenly stopped gaining access to internet via my broadband. Was working ok all day,then suddenly stopped. It seems that the DHCP Client Service has stopped (so can't get an ip address). I have tried starting/restarting but then get the message Error 5: Access Denied (although I have admin rights). I have trawled the web and it seems quite common and appears to be a windows bug. However,no known fix! In case it was caused by an automatic windows update that day, I tried restoring to a previous version but this won't work either! Any solution known?

I go to event viewer and see this: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x8CA98215C731. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.
My internet will randomly stop working, but my computer still says its connected to the internet. I go to diagnose the problem and my computer says there is no problem but event viewer says differently. Can anyone help me with this? It happens once every hour or so and i have found no way to fix it, it just randomly fixes itself sometimes and sometimes i have to restart. This just started happening when i got a new computer, i had no problems with my old laptop.

Reference this thread:

Amazing Network Problem.

Router: D-Link d-524 V4000
Ethernet: Nforce via mobo Gigabyte GM-A570SLIv2

I am having similar problems as with the linked thread. What happened with me was I needed to download drivers for my 2nd pc because the wireless had issues. So I unplugged my Cat-5 cable from my main pc that was working and then plugged it into my 2nd pc. I downlaoded the drivers and then reconnected the cable back into the main pc. That's when the problems began. My 2nd pc is the exact same setup as my main other than the processor is different and it works great. Things I have done:

1. Connected straight to DSL modem.
2. Reset both modem/router
3. IPconfig shows the 169 IP.
4. Pinged the NIC with no loss of packets.
5. Reloaded the drivers via mobo CD(Vista x64)
6. Started in safe mode w/networking
7. Restarted DHCP Client
8. Verified configuration matched the other pc.
9. Reinstalled Iv4 using c:/windows/inf
10. Bought a PCI adapter in case the mobo connection was bad. Didn't work either.

I can't even access the router or modem on the main pc. I tried a static IP but will try what was suggested in the linked thread when I get home today. If you need snipits I can do that once I get home. I'll provide anything you need. Most of the snipits in the link thread have the same info as mine would that's why I linked it. Thanks in advance for the help.

I have a Dell Inspiron 1525 running Windows Vista Premium.

I've been having problems connecting to the internet with my wireless card. The best I can do is 'connected with limited access.' I think I've tracked it down to the fact that my DHCP client is not running. When I attempt to start it, I get the message: error 5: access is denied. How can I solve this problem?

We are running an NT 4.0 Server w/ SP6a applied. We also have ZoneAlarm, ComSocks (LinkByte), and WebWasher.

The problem that we have is, approx 3 months ago, our ISP had some DHCP problems. Since then we have not been able to renew an IP lease. In fact, when the lease expires, to get it back we have to re-boot the server.

The ISP provides a cable modem. We've recently replaced it (as of yesterday) and we still have the same problem.

Here is what happens: Eudora can't make connections for email. So, go to Control Panel, Services, and scroll down to DHCP Client and it is stopped. So you "start" it. If it starts, then Eudora can get mail (and all of the other internet connections now work -- we just use Eudora to determine if we've lost the connections as opposed to things just being slow).

Now we get a DHCP message that tells us that our lease has not been renewed. Click OK, and start a DOS window. Run IPCONFIG /ALL and you will see that the ISP's NIC has no addresses! Go to Control Panel, Services, and scroll down to DHCP Client and it is "stopped". Now attempt to "Start" it. If the lease has not expired, it generally will start. If the lease has expired, then we have to reboot the server to get a new one.

This procedure is typically being done 3-6 times a day. And on a weekend (if I'm in working), I may have to do the re-boot part 3-6 times a day!.

So, what we'd like to figure out is, what did we change on ou... Read more

A:DHCP Client service stops

Went to Zone Labs web site to check on a few things about ZoneAlarm. They mentioned some things that are supposed to be specific to ZoneAlarm PRO having to do with an ISP PINGing (or some such) to determine if you are still there. If you don't respond, then they knock you off (basically, early terminate your lease).

Well, the solution to our problem is the solution defined for ZoneAlarm PRO -- define your ISP's DHCP server(s) to ZoneAlarm as a "trusted" computer while setting your LOCAL security to MEDIUM. Then if your ISP also has one or more "testing" (probe to see if user is connected) IPs, you must add those as well. Generally, they said watch the Alerts and it is probably the last alert listed that contains the IP address from your ISP that needs to be added (this is immediately after losing connectivity).

This was a new feature of ZoneAlarm that we somehow missed having been added to 2.6.88 (we had been at 2.1.44). Having our ISP have DHCP problems and doing this upgrade about the same time with two others made this one a real pain to determine. [Our ISP finally admitted this week that in our area they have been having connectivity problems beyond DHCP server anomalies -- "regular" unscheduled outages.]

I got this error message after my system took itself off my dhcp server. I was online when this happened and evertything was charlie-charlie prior. DHCP client but after each try, it stops automatically. I'v restarted, I'v sfc/scannow. I'v tried restoring but realised i dont have restore points. i'v tried repairing with my OS cd but realised vista's repairing isnt like xp (it doesnt actually recopy the system files).
The network connectivity icon is blinking ok but it cannot read the domain name of my network. In the network and sharing centre, the status is "Identifying... (Public network)". In the Local Area Network Status, Packets are being sent but not received. I think I should be able to browse if i assign ip address manually but i would like to correct this error.
Right now, I am out of ideas.

A:DHCP client service not running

Could you please link to the topic?

--

Just going off the topic title (DHCP client service not running) I think this should fix your problem:

1. Go to Start
2. Click Run and type services.msc and press Enter or click OKAY
3. Look for the service DHCP Client
4. Right-click the service, Properties
5. Change the Startup type to Automatic - the service will now automatically start on boot.

To start the service now after setting the startup type to automatic in the properties look under "Service Status" click "Start".

Hello again! I've encountered a new problem that I'm having trouble fixing if you need me to do the zip and all that let me know and I'll work on it but it's pretty specific to this. Even so more info is good so let me know if you need it.

The crashes occur while using FTP to transfer files to anything within my network. I'm currently using FireFox's FireFTP program to do so. I am able to connect to my server but unable to transfer anything since as soon as I do that's when my computer crashes. I looked through the event logs and found this following message:

The IP address lease 192.168.1.2 for the Network Card with network address 0x001A70A37011 has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).

Apparently this causes a critical error and I get that weird no BSOD but can't do anything type of crash. If anyone can help me out I'd much appreciate it thanks.

A:DHCP-Client Error causes Crash

How many computers are on your network? Set them all to static IPs starting from 192.168.1.2 and going up (192.168.1.3 etc...) and see if it makes a difference.

Hey, everybody?i'm new here so bear with me, I want to be as detailed as possible about all the screw ups that got me here .

I lost my DHCP Client. It is my fault. It is no longer in services or anywhere. It all started when I isolated DHCP Client into it's own svchost.exe file to root out a rogue service in the svchost.exe that was eating CPU (after doing a thorough clean with Avira, MalwareBytes, and Spybot S&D in Safe Mode). DHCP was the culprit, but now i can no longer find DHCP Client in Services. I was unable to reverse the modification I made because i didn't know the proper syntax. Here's the syntax I used to CREATE this problem for myself:

First, I made a copy of svchost.exe and named it "svchost_dchp.exe" using these commands:

copy c:\windows\system32\svchost.exe c:\windows\system32\svchost_dhcp.exe

Then, I configured it to start in it's own thread using the new name (but I SERIOUSLY think i left the "-k netsvcs" out!):

sc config dhcp type= own binpath= "C:\WINDOWS\system32\svchost_dhcp.exe -k netsvcs"

Yes, I know now - if i absolutely HAD to mess with this, i should have simply used the "type= own/share" switches instead of going through all that?and to make matters worse, i DON'T know how to change this back so that DHCP is in it's original svchost.exe again..

I ran Repair Console. Nothing. I delete the ethernet driver and... Read more
