Nothing different: the firewall doesn't even get to see the name. By the time
the packet reaches the firewall, the IP address has already been determined
(done by a DNS lookup on the client PC). Most likely the firewall admins have
specifically added a rule to allow access to the Microsoft news groups. It's not
uncommon for corporate firewalls to not allow access to NNTP in general.
