How to modify the Windows default 3389 remote port

Port 3389 is the service port of Windows 2003 Server Remote Desktop, through which connection tools such as Remote Desktop can be used to connect to remote servers, and if connected, enter the username and password of the system administrator. It will become possible to operate a remote computer as if it were a native, so the remote server generally shuts down the value of the port.
To modify the values, you need to modify two places in the registry:
First place:
[HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL\TERMINALSERVER\WDS\RDPWD\TDS\TCP] PortNumber value, the default is 3389, modified to the desired port, such as 6000
A second place:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\winstations\rdp-tcp]
PortNumber value, the default is 3389, modified to the desired port, such as 6000
Now it's OK. Just reboot the system.
Attention:
If you set the port filter, specifically in the TCP/IP property settings, there is a "advanced" button, and then the last "option" buttons inside the TPC/IP filter, please be sure to allow the changed remote port, such as 6000, otherwise remote;
