In Windows ''Teletubby'' mode (I use Classic), click Start, Control Panel, Security Center, Firewall. Click ''Turn Off Firewall''. Windows will warn you not to turn off the firewall. Do it anyway. Install a third party firewall. I prefer Zone Alarm, but I know others that are just as happy with McAffees and Nortons firewalls. ZA, Norton and McAffee firewalls block in both directions, Windows firewall only blocks incoming conections.
I dont know if XP comes with a firewall but im assuming it does caue its stopping alot of things from opening. Does anyone know how to config the firewall? Thanks for the great help guys!
