I have been having problems with Xp SR2 since Sunday and it's a FRESH INSTALL!!!!!! The firewall stopped working and can't be configured and the automatic updates keep installing the same thing over and over. So....... I donwloaded free ZoneAlarm firewall and enabled "High security stealth mode" which works pretty good. IP address sites can find Comcast Michigan, but no further. I also turned off automatic updates, which I was stupid enough to leave on in the first place. People who trust Microsoft are the same type of people that trusted Hitler. LOL!
