Changing the RDP operating port

Microsoft's Remote Desktop Protocol, built into Windows Server 2003, Windows XP and Windows 2000 Server Editions runs on a default TCP/IP port of 3389. For security reasons, you may wish to change this.

Please note: changing the RDP operating port will prevent the Remote Assistance feature from working correctly.
To change the RDP operating port:

  1. Use a registry editing tool to navigate to the following key:

  2. Insert or change a value with the following details:
    Data Type: DWORD
    Value Name: PortNumber
    Value: The number of the port you wish the RDP service to operate on, e.g. 12345

  3. Restart your computer for the changes to take effect.

Note: It is best to avoid any ports that are commonly used by other protocols. For help in doing this, see our TCP/IP port list.

Please note: All numeric values are shown in decimal notation.
