Change Remote Desktop port
From TSG Library of Knowledge
Problem: By default, Remote Desktop listens on port 3389. How do you change it?
Solution: Use Registry Editor to edit the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
Next time you try to connect to that computer, you'll need to enter a colon and the new port number. For example, you would open Remote Desktop and type server:3391. (When a port number isn't specified using the colon, the Remote Desktop Client will assume you want to use port 3389.)
