Who Can Install Active Directory on Windows Server 2012?
If you are going to be creating the first Domain in a new forest, log on as the local Administrator. If you’re adding a new domain in an existing forest, be a member of the Enterprise Admins group for the forest you’re going to join. To add a new domain controller to an existing domain, be a member of the Domain Admins group.
Once you’re logged into the Server with the correct account, you’ll next add the Active Directory Domain Services feature to your server. You can install the Active Directory Services feature on to Windows Server 2012 by both PowerShell and Server Manager.
The fastest method of installing features in Windows Server 2012 is with PowerShell; let’s take a look at the steps needed to accomplish this.

It doesn’t get any easier than that, but in case you want to do it the hard way, I’ll show you how to add the Active Directory feature to your Windows Server 2012 using Server Manager, too.
Install Active Directory Domain Services on Windows Server 2012 with Server Manager
- Open Server Manager, then select Manage and click on “Add Roles and Features”
- Click Next on the “Before you begin” window
- Select Role-based or feature-based installation and then click Next
- Click Select a server from the server pool, click the name of the server to install Active Directory Domain Services to, and then click Next (If you wanted to install this on a remote server, you have to first create a server group containing the remote server)
- Click Active Directory Domain Services. When the Add Roles and Features Wizarddialog box opens, select Add Features, then Next
- On the Active Directory Domain Services page, review the information and then clickNext
- On the Confirm installation selections page, click Install
- On the Results page, verify Installation succeeded, and click Promote this server to a domain controller to start the Active Directory Domain Services Configuration Wizard
The nice part about using the Server Manager method is that it takes you directly into running the Active Directory Domain Services Configuration Wizard, which is the utility which replaced the deprecated dcpromo.
Now that you’ve installed the features, you will need to promote the server into a domain controller.
