Active Directory is Microsoft's trademarked directory service, an integral part of the Windows 2000 architecture.
Authentication takes place on domain controllers. Each person who uses computers within a domain receives a unique user account that can then be assigned access to resources within the domain. Starting with Windows 2000, Active Directory is the Windows component in charge of maintaining that central database. The concept of Windows domain is in contrast with that of a workgroup in which each computer maintains its own database of security principals.
