Try the following...

Repairing the Winsock and TCP stack on XP

Windows XP provides several commands to repair issues with the TCP protocol stack. The commands increase in the degree that they are likely to impact other software on the system, so it is best to progress through them one at a time to limit the other software that has to be reinstalled or repaired afterwards.

First try, "netsh winsock reset catalog" in a command window. If that doesn't work, try "netsh winsock reset" and finally try "netsh int ip reset ipreset.log". All three of these commands should be run in a command window.

Lets do a couple of things. Run ipconfig/all and post back all the info.
Also, in a command window
type nslookup
at the new prompt enter 'set debug'
then enter www.google.com
then exit

post back all the output from the session
