On the domain controller, open the group policy management tool.
Create a new group policy.
Enter a name for the new group policy.
In our example, the new GPO was named: MY-GPO.
On the Group Policy Management screen, expand the folder named Group Policy Objects.
Right-click your new Group Policy Object and select the Edit option.
On the group policy editor screen, expand the Computer configuration folder and locate the following item.
Right-click on the Registry option and create a Registry entry.
On the registry screen, perform the following configuration.
To save the group policy configuration, you need to close the Group Policy editor.
In our example, we configured the RDP service to use the TCP port number 3333.
Congratulations! You have finished the GPO creation.
