This article will show you how to install a new Domain Controller on Windows Server 2012.
With Windows Server 2012 the setup is completely different and DCPROMO no longer exists.
The installation can be done using the server manager or PowerShell , In this article I’ll use PowerShell for the install and server manager for the configuration.
First step is to open PowerShell and type:
Install-WindowsFeature -Name ad-domain-services -IncludeAllSubFeature
Once installation is completed start Server Manager
In the Right top corner Click on the alert icon and click on Promote this Server to a domain controller.
In the Wizard screen select the option you are after and follow the Wizard.
