No other firewalls. But maybe in the router but that wouldn't make any difference cause it was working before with the router and I didn't change anything with the router. I think it was sp2 that changed the firewall settings and nats maybe. I just noticed that I am running Windows Messenger and not MSN Messenger. Suppose there are any differences? Also maybe there is an update for Windows Messenger. I am running version 4.2. I'll check for a later version. Have you guys installed sp2? And if so, have you had any trouble with
Windows Messenger?
