In this how-to, we will walk you through Configuring Active Directory in Windows Server 2012.

Active Directory also known as AD, is a service that comes with many Windows Server Operating Systems. It is used to manage Domain Networks distinguishing an administrator user and normal users.

Once the AD DS role is installed, the server will need to be configured for your domain.


– A Server with Windows Server 2012. If you do not have a server already, you can visit our VPS Hosting page and spin a new server up in under 30 seconds.

– Active Directory(AD) installed on your server. See the following article “Installing Active Directory in Windows Server 2012” for more information.

Configuring Active Directory

Open the Server Manager from the task bar.

Open the Notifications Pane by selecting the Notifications icon from the top of the Server Manager. From the notification regarding configuring AD DS, click Promote this server to a domain controller.

In server manager select Promote server to a domain controller
