Note: If you want to have a different Computer name, you will need to change that manually before you start the process below and restart after changing the computer name.
You will need to install the AD Domain Service management tools before you are able to run the powershell
Install-windowsfeature -name AD-Domain-Services –IncludeManagementTools
When the management tools are installed you can drag and drop the powershell file to powershell window and press Enter and as soon as you do that it will ask you for the SafeModeADministratorPassword.
After you press Enter it will start the installation process
When finished it will let you know that server is going to be restarted automatically.
After restarting the server, this is how the Full computer name became.
