How to change Terminal Server's listening port

Use Registry Editor at your own risk.

To change the default port for all new connections created on the Terminal Server:

1.	Run Regedt32 and go to this key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp NOTE: The above registry key is one path; it has been wrapped for readability.
2.	Find the "PortNumber" subkey and notice the value of 00000D3D, hex for (3389). Modify the port number in Hex and save the new value. To change the port for a specific connection on the Terminal Server: • Run Regedt32 and go to this key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\connection NOTE: The above registry key is one path; it has been wrapped for readability.
3.	Find the "PortNumber" subkey and notice the value of 00000D3D, hex for (3389). Modify the port number in Hex and save the new value. NOTE: Because the use of alternate ports has not been fully implemented for Terminal Server 4.0, support will be provided as "reasonable effort" only, and Microsoft may require you to set the port back to 3389, if any problems occur. Use Registry Editor at your own risk.
