Hi Tiago, By not including the other TCP ports I've listed messenger will not download. If you begin a session and have someone send you a file accept it and it won't work. You can look at the ISA firewall logs and see that all the other ports are "connection denied". I have friends that are always saying I need to upgrade to the new messenger and I also need to allow file transfers. Nope I won't do it.

Have you filtered them using IP Packet filters? The default MSN Messenger Protocol Definition doesn't include these ports, not even as secondary.
