This is typically the root DC for the entire AD forest.Windows Server 2012-2016 does not provide a 32-bit version of adprep.Running adprep is optional before adding a Windows Server 2012-2016 domain controller.This is because Windows Server will run it automatically for you as part of the domain controller promotion process. If you are upgrading from a 32-bit edition of Windows Server, such as Windows Server 2003, you cannot run adprep manually. When promoting a Windows Server 2012 or later as a domain controller, the AD forest functional level must be at least Windows Server 2003 or higher. For detailed information on using adprep see Running and the Microsoft command reference. It is not harmful if you run adprep multiple times or run it on the wrong DC.It will display an error message and quit without changing anything.
