Change the listening port for Remote Desktop on your computer

When you connect to a computer (either a Windows client or Windows Server) through the Remote Desktop client, the Remote Desktop feature on your computer "hears" the connection request through a defined listening port (3389 by default). You can change that listening port on Windows computers by modifying the registry.

1. Start the registry editor. (Type regedit in the Search box.)
2. Navigate to the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber
3. Click Edit > Modify, and then click Decimal.
4. Type the new port number, and then click OK.
5. Close the registry editor
6. Open the port from Windows firewall.
7.  restart your computer.
