Windows: Change Remote Desktop Port

If you check Event Viewer of your server and see that there is many Audit Failure in Task Category Logon, you should change the port of remote desktop immediately.

Change port value (select Decimal when changing) of the registry PortNumber in:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp

PortNumber of Remote Desktop

After changing, restart your server.

To connect to your server with new port (e.g. 3333), use the following information:
Your_Server_Name:3333
OR:
Your_Server_IP:3333

Make sure the firewall of your computer doesn't lock this new port.
