• Locate the registry key called HKEY_LOCAL_MACHINE\System\CurrentControlSet\Contro l\TerminalServer\WinStations\RDP-Tcp\PortNumber
• Click the subkey PortNumber, find the Edit menu, choose Modify, then select Decimal.
• Type your desired port number. It should be xxxx or xxxxx, and should not conflict with another running service (choose a high port number).
• Click OK. Exit Registry Editor. Restart the system.

The server's port for RDP connections will now be updated.

NOTE: To connect to Windows server on the new port, you will need to specify the port in Remote Desktop Connection or your RDP application of choice. This is usually done by entering the server’s IP address and port in the following format:

0.0.0.0:33994 (Where “0.0.0.0″ is the server’s IP address, and “33994″ is the RDP port number.)
