How to Reset the TCP/IP Stack
XP, in its infinite wisdom, will not let you reinstall the TCP/IP stack, which is the common way to resolve serious or insurmountable networking problems with the Windows OS.
Cheers Guys.
If you do have a problem and this would seem to be the only viable solution, here's how you reset it (which is the next best thing):
Open a command prompt and type:
netsh int ip reset C:\resetlog.txt
Then reboot the PC.
Done.
