In a customer PC (Windows XP SP3), suddenly the network went down: the network adapter appears with an error mark. I replaced the network card, but the new one does the same thing.

When I enter IPCONFIG, XP shows this error (in standard and safe mode):

Internal error occurred 
Request not supported 
Unable to query host name 

If I start the system with a boot cd the PC runs fine, so the problem seems to be in the XP installation.

I tried:

  • uninstalling and reinstalling the network card in the Device Manager
  • disabling and reenabling the card
  • netsh int ip reset
  • netsh winsock reset catalog
  • and a couple of "reset" programs (WinsockxpFix.exe, etc)

with no luck.

Is there any way to fix it without reinstalling XP?

TIA, Pablo

  • Were any windows updates (automatically) installed recently that could have broken it? (history available @ update.microsoft.com)

I would have bet the Winsockfix would have done it. It sounds like the TCP stack is screwed up. Have you tried this KB article?


I like uslackrs response since it has the fixitnow thing!
