I've been chasing this problem on and off for about three months with limited results.
I lost my internet connection, and I get the following message, "unable to contact your DHCP server".
This occurred after a system reboot and I have been unable to get this computer back online since that time.
At the time it went down my security software was reporting a virus that it could not remove, but that had been going on for a week or so and it didn't seem to be causing any system problems.
I later took the computer to a professional who scanned and cleaned it, and replaced the security program with a different one, AVG 9.0.
At the time I lost connection I contacted my DSL provider, after performing some service tests the tech pronounced the problem to be on my end.
At that point I got out my backup computer, which also runs on WinXP SP3 on a somewhat older platform, and it connected with no problem.
I than swapped the hard drives between the two computers. The backup drive, now in the computer which origanily had been giving me trouble, connected without a problem.
It was at this time, I took the infected drive to be scanned.
Since that time I have been following threads on various forums without much luck.
I have only gotten a connection twice. The first time was before I got the router, I was swapping the cable from one computer to the other and I got connection but it only lasted until I did a reboot. I decided
the Bad Boy had hijacked the IP address that had been assigned to the other computer.
Shortly after adding the router I was able to get online again, this time through the router, after reinstalling the Ethernet Adapter I was able to get online for 4 or 5 hours and did several reboots as I was trying to establish home sharing for Itunes and also printer sharing, I was unsuccessful with both, The only significant event on the last reboot was that Windows installed a bunch of updates. That was three weeks ago.
Since than I have had no luck whatsoever. The system can't find the router nor will it connect directly through the modem either.
Some of the things I have tried are as follows:
swapped cables around
bought a new modem
changed to a different NIC
ran netsh int ip reset
ran netsh winsock reset
ran LSPfix
ran winsockxpfix
pinged 127.0.0.1 (results below)
uninstalled and reinstalled Ethernet Services
tried safe start with network services
tried partial clean boot (probably same as above)
checked all settings suggested in the threads
compaired settings and registry keys to working computer
I'm at my wits end on this any help would be appreciated.
