How to Change the RDP Port for a Windows Server


The default Remote Desktop Protocol (RDP)  port for Windows servers is 3389.  This article introduces the steps to change the RDP port for a Windows server.

1 Change the RDP port on registry

There are two methods to change an RDP port on registry.

1.1 Change the RDP port by modifying the registry manually

Press “Windows + R”  to open Windows Run dialog. Type “regedit” in the Run box and press Enter to open Windows Registry Editor.
Navigate to the following registry subkey: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber
Click Edit > Modify, and then click Decimal. Type the new port number, and then click OK.
Note: The recommended range for RDP ports is 1024-65535.

1.2 Change the registry with PowerShell Command

Open Windows PowerShell (Type PowerShell in the Search box).
Run the following command:
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp' -Name 'portnumber' -Value 33899
Note: 33899 is the RDP port changed in the last step. Please change the parameters according to your settings.
