Here’s a quick reference to change the remote desktop protocol port number. This is helpful if you have multiple servers you need to access on a corporate LAN or if you want to create a backdoor for your business computer. Make sure to open the port in your firewall too!

1. Start Registry Editor.
2. Locate and then click the following registry subkey:
HKLM\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\PortNumber
3. On the Edit menu, click Modify, and then click Decimal.
4. Type the new port number, and then click OK.
5. Quit Registry Editor.
