Installing Active Directory on Windows Server 2012

Home / Installing Active Directory on Windows Server 2012

Active Directory (AD) is Microsoft’s implementation of directory service for Windows domain network. It uses Lightweight Directory Access Protocol (LDAP) version 2 and 3, Microsoft’s version of Kerberos, and DNS.

Active Directory is used on Windows Server. Usually a dedicated server for Active Directory is referred as Domain Controller. A Domain Controller authenticates and authorizes all users and computers in a Windows domain type network. It also assign and enforce security policies for all computers and installing or updating software.

In a network, there should be only one Active Directory Domain Controller. Or, at least there is one master and only two slave Domain Controller at maximum for load balancing.

Like any service on Windows Server 2012, Active Directory Domain Service (AD DS) is implemented as server role. This article will discuss about how to install Active Directory in Windows Server 2012.

From “Server Manager” Dashboard, select “Add roles and features”. This will launch the Roles and Features Wizard allowing for modifications to be performed on the Windows Server 2012 instance.

Configuration

Once Active Directory Domain Service is installed on the server, we can start configuring our domain. I will assume that this is your first time configuring.

Open the “Server Manager”, if you have not opened it yet.

Open the Notification Pane by selecting the notification icon from the top of the Server Manager. It looks like a flag, and should have an exclamation mark on it. From the notification regarding configuring Active Directory, click “Promote this server to a domain controller”.
