IP Network stack on Windows 2000 appears to be dead though loopback ping to 127.0.0.1 is working

I cannot connect to the internet nor connect this PC to another PC for a virus scan.

Anyone any ideas ?

Working for a long time until. Do not know what caused this failure.

PC has IP and DNS dynamically allocated.

Connects to broadband through modem router. Modem router is fine. Modem router assigns IP.

Web pages will not load. Email cannot be collected. Ping to modem router fails. Only loopback ping works.

Wandered if it was sasser but have done a scan. Not that. Scanned it with wirus utility with updates about a month old. This picked up some java malwae which I deleted.

Have checked registry and cannot see anything in local user ...windows --> run that is starting up that is crippiling external software.

Hi kes3,

Have you tried resetting the tcp/ip stack and winsock?
Here's a tool to do both at the same time:

(don't let the name confuse you, it works for all versions of windows)

>>169.254.99.96<<
That means it's NOT obtaining a valid IP from the DHCP server. It's an APIPA address as explained at http://support.microsoft.com/?kbid=220874 
That means that either the DHCP server isn't giving out adresses, or the NIC isn't receiving one.
The winsockfix which I posted above might surely help in this case.
