One of our work computers had some form of "automatic update" loaded last night from Microsoft. OS is XP SP2.
This one system cannot access any web sites. All other computers on our network are fine, as was this one yesterday. Regardless of browser, I see something like "network link was interrupted while negotiating a connection."
The computer sees our internal network servers and printers, can "ping" any valid domain on the www such as www.google.com
But it cannot open an HTTP session, even with a host local to our network.
No proxies are set, no IPSEC filtering I can see, no network config IP traffic controls. I tried the "netsh winsock reset catalog" and also the winsockxpfix.exe recommended in another thread.
No luck. Ideas?
