How can I add a new RDP listening port to Windows 2000/2003 Terminal Server?

You cannot add a new listening port to your Terminal Server via the GUI (Terminal Server Configuration in Administrative Tools) because there is no option for changing the listening port via the GUI.

What you need to do is create the new RDP listening port via the registry.

This document contains instructions for editing the registry. If you make any error while editing the registry, you can potentially cause Windows to fail or be unable to boot, requiring you to reinstall Windows. Edit the registry at your own risk. Always back up the registry before making any changes. If you do not feel comfortable editing the registry, do not attempt these instructions. Instead, seek the help of a trained computer specialist.
  1. Run Regedit.exe on your Terminal Server.

You can now connect to the new port by using the “old” Windows 2000 Terminal Server client. A better option is to use the RDP client found in Windows XP, or even better, the newer Windows Server 2003 SP1 RDP 5.2 client (Download RDP 5.2).
You’ll need to configure your TS client to connect to the new port. Although changing the connection port on the RDP clients is quite easy, you CAN also change the connection port for the TS client. See Related Articles list for more info.
