Tried the netsh winsock reset but no web access, nslookup & ping OK

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 or www.yahoo.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?

Your ipstack could be corrupted. I know you ran netsh but still try running this and rebooting:

Have you double checked the tcp/ip dns servers? Are they still obtain (or whatever your servers are set as)?

Also, make sure there is no spyware on that system, download this:
www.superantispyware.com
run it and reboot as well.
And try logging into the computer with a different username/profile and see if the same thing happens.

run command in command prompt.

netsh interface ip reset c:\reset.log
ipconfig /flushdns
shutdown -r -t 0 -p

after restart, if it still does not work.
You may want to check the proxy configurations. Making sure the proxy address is correctly entered and using the right port.

Good luck.

Last night, one of my staff suggested installing ZoneAlarm as an outbound trap for Port 80 requests.  It prompted to allow the outbound traffic, but the browsers both came up blank.

There were no Network Device Drivers to roll back to, so I could only assume something higher in the stack creates this problem.

The first software to uninstall was LogMeIn, with no changes.   Then I uninstalled the Microsoft AVG software and VOILÁ!   We have access to outbound port 80 requests.

We'd picked up an update on 10/21/08 to AVG 8.0 that must either have been a bad release or corrupted.

Case closed, thanks for the help!
