How to Change Remote Desktop Port in Windows

Remote Desktop is a very useful feature of Windows operating system that allows the user to remotely connect to the computer from any computer to the computer where RDP is enabled. By default, Remote Desktop uses port 3389. Since this is a common port, and if RDP is enabled on Windows, it will use this port which poses a security risk therefore it is highly recommended to change this port.

You can implement an account lockout policy to lock the account after (X Number of failed log-in) attempts. However, you don’t want anyone to login to the RDP and attempt brute force attacks.

Note: When you change Remote Desktop Port, you must type the new port number when you try to connect to this computer. If you have a firewall installed, you may need to configure your firewall to allow the new port before you can connect to this computer using Remote Desktop.
