State of system :
I'm using the builtin Firewall
I can login to my .Net account through Windows Messenger
Cannot send files...
Cannot establish Video/Audio connection (MS Portrait, Netmeeting)
but more important, I cannot connect to discusion rooms (like Irc)
"...try later..." (I'm having the french version of XP)
I would really like to be able to connect to the Chat feature ... :(
