Windows 7: 32 bit apps cannot connect to network. 64 bit apps can.

32 bit apps cannot connect to network. 64 bit apps can.

I can only connect to the network using 64 bit applications on Window 7 Pro SP1.

The problem occured after installing the latest version of iTunes (may or may not be related). I uninstalled iTunes with no change. IE 32 bit crashes after opening. Firefox opens but gives Server Not Found error. I cannot connect webservers on the local network with Firefox either. Filezilla will not connect to local or remote servers. VNC will not connect to local servers - IE 64 works fine and command line tools like ftp and telnet to internal and external sites works fine - this is not a DNS, Firewall, or Routing issue.

Same results in Safe Mode
sfc /scannow runs clean.

I reset the winsock, uninstalled all my network adapters, including the drivers and resinstalled them. Rebooted multiple times.

Unfortunately I just discoved that System Restore was not enabled so I can't roll back.

I doubt this is malware related as I have multiple levels of defense (postini, SpyShelter, Symantec Endpoint) and outside of iTunes have not downloaded or installed anything or even visited unusual websites. I'm about to do a deep scan that will probably take a few hours just to play it safe.

Please! Does anyone have any suggestions? I see plenty of posts about similar issues but either they never get resoved without a rebuild or the winsock reset works.

More info:

VNC gives the error: "Unable to initialise Winsock2" while Putty: "Unable to initialise winsock"

Netsh int ip reset reset.txt hit responds:
Reseting Global, OK!
Reseting Interface, OK!
Restart the computer to complete this action.
BUT there is no reset.txt created in the directory I run it from (c:\temp), even if I sepecify a path for the log file... This seems curious.

The virus scan is still running (clean so far).
