Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

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) –  iainlbc Apr 24 '10 at 2:36

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?
