Can't connect to the internet

I have three machines that I use through my Linksys router, two desktops
(wired) and one laptop (wireless). One of my desktops (running XP SP2) can
suddenly no longer make a connection to the internet or download e-mail in
Outlook. It is able to talk to the router and can see the other computers
attached to it, but can't make an internet connection. The other two
machines are having no problems. Surprisingly, a gnutella-based file sharing
application that I have running on the maching still can make a connection
and exchange files.

I have tried all of the usual fixes...checked cables, replaced cables,
rebooted the PC, powered down the router and the cable modem, bypassed the
router and wired directly into the modem, even unplugged the ethernet cable
going into the PC and plugged it directly into the laptop (internet worked
fine on the laptop).

Everything worked fine this morning--I'm considering doing a system restore
next. Anybody got any other ideas?
 
Can you ping a public IP? If yes, can you ping yahoo.com? Or this step by
step troubleshooting may help.

I'd look for LSP / Winsock corruption first.

Next, look for a DNS problem.
