I would agree 100% for home users, but server admins should know better 
(IIS, bind, sendmail, RPC(unix), ssh, etc exploits).

Firewalling internal networks can be tricky at best *if* you are really 
doing Microsoft file sharing, Samba, CIFS, etc.  It hits you where it 
hurts and you can't necessarily block it (no more than you can block 
http for IIS or Apache weaknesses, it's self-defeating).
