If you really want.. You can.

You can start by opening all the ports as stated in a whitepaper, downloadable from the Microsoft site, that explains all ports that have to be opened between a frontend and a backend Exchange 2003 server. This will involde opening up all SMB related ports (starting with 135/TCP), but a dozen more will follow.
Furthermore, some ports will be dynamically assigned to the clients. You can limit the range of ports this will be though; that would require you to modify each domain controllers registry and reboot them.

The only open port would have to be 443 (if you use SSL/HTTPS)
