I've had some success fixing TCP/IP strangeness by changing some
properties (like the host address) and then changing them back - less
drastic than removal/reinstall. This causes the system to rebuild some
driver tables and reinitialize some values. Needless to say, there are
two reboots involved :-).

But to answer your question, call up the network properties, select
TCP/IP protocol, and remove it. Then reboot. Then call up the network
properties and ask to add a protocol - add TCP/IP. Then reboot.

Have your Windows installation CD handy (if you installed from one)
when you do any of this!
