Installing Active Directory on Windows Server 2008 R2

Installing Active Directory on Windows Server 2008 R2

Active Directory, introduced with the Windows 2000 server is a directory service, which stores information about the network components, authenticates network users, and enforces security policies. It works by tracking “objects,” which can be users, services, resources, or systems, and then resolving their names to the actual objects. The advantages of Active Directory are the better security management, easier administration, easier assignment of permissions to object, and the use of single source that can find any object on the network.

Active Directory has several different components (you can learn more about the active directory architecture by going to this page) and the Active Directory service is closely integrated with the Domain Name System (DNS). The directory service in Windows Server 2008 and later is called Active Directory Domain Services (ADDS).

Installing Active Directory Domain Services (ADDS) in Windows 2008 R2

Click Next, Next again, and then the Install button

Wait for the installation to finish and click the Close button

Reboot the server. Once Active Directory Domain Service is successfully installed, you should see it under Roles in the Server Manager console. Note the message under Active Directory Domain Services “This server is not yet running as a domain controller” and click the link that follows the message in order to start the installation wizard (dcpromo.exe).
