I did not know this, but it turns out Mircrosoft keeps a list of all the ports that various MS services use. This
list is available for download as an Excel spreadsheet from the Microsoft site.

Good find, never saw that document before. Too bad it doesn't include the ports used by Windows Small Business Server 2003. You can find a list of those ports at http://thebackroomtech.wordpress.com/2008/06/04/ports-to-open-on-a-firewall-for-sbs-2003-communication/
