Similar to the subject I might just jump in here and let XP users know something.
XP's built in firewall isnt the best to rely on either because it only blocks incomming. Not outgoing.
The point of not letting outgoing traffic... out, is that if you have an undetected trojan/virus on your PC, you can block it from trying to communicate to the outside world, protecting your friends and everyone else.
It be best to disable this firewall and download another. (ZoneAlarm is a good one)
