Similar to previous versions of Windows Server, you start the process of making a server into a domain controller by adding the Active Directory Domain Services roles to your computer. However, in Windows Server 2012, you do not run dcpromo to promote your server to a domain controller. In Windows Server 2012, dcpromo has been deprecated.
So what replaces dcpromo in Windows Server 2012? There are now two ways to promote your server to a DC. The first option is to use PowerShell. This provides the ability to script the process, save the script, or batch the process out to multiple servers. The second option is a task made available in Server Manager that can be run to begin the promotion wizard.
