Originally known as NTDS, AD (Active Directory) is a directory service first provided in Microsoft Windows 2000 (although was shown in 1999 on Windows NT). Active Directory is often managed and controlled through the MMC (Microsoft Management Console).
The Active Directory is a directory service that is stored in the NTDS.DIT file. It provides a simplified query for administrators and users to manage resources, sites, services, and users on a network.
