system error: An internal error occurred: the request is not supported

this is what I get on a system when I type ipconfig... windows xp pro sp 2.... tried all the standard netsh stuff... tried winsockxpfix... tried reinstalling the nic, tried different nics, tried disabling and using a wireless nic... any ideas?

found the problem, virus kill the tcpip.sys file in c:\windows\system32\drivers....

weird!
thanks
