Windows XP computer not able to access shares, or communicate with 4 Win 7 Pro computers on same network.

So i have a small peer to peer network, 5 computers - 1 Win XP Pro/4 Win 7 Pro. For some reason, the Win XP computer stopped communicating with the other computers. Here's what I've tested so far.

The Win XP computer cannot ping any of the other computers, and the other computers cannot ping the Win XP.
The computer is remotely accessible via logmein, and can get online, so i think I've eliminated the network card/cable.
The other 4 Win 7 computers can communicate with each other.
Windows firewall is disabled.
I found a reg key that supposedly helps or corrects these issues on Win XP computers.
I've also disabled the antivirus software.
I updated the drivers on the network card.
And yes, i rebooted. :)

The interesting thing is, i was out of ideas, so i ran a winsock reset, rebooted, and i was able to see the network! THEN, i rebooted again, and it was back to the way it was, nothing. Again, this was working fine as of 2 days ago.

Any help on this would be greatly appreciated.
