Long time user. Wouldn't connect this morning AT ALL. Never have any problems. Tried the exceptions route, it's there, tried anti virus off, nothing. Tried MS firewall settings and exceptions, it SHOULD go through. NEVER had any problems before. I DID just do a SP3 upgrade so if THAT's it, anybody got any ideas? SYSTEM DELL 3500 with XP media, 1gb ram, cable modem,,NO router,
