Global catalog. Contains information about every object in the directory. This allows users and administrators to find directory information regardless of which domain in the directory actually contains the data. The global catalog is hosted on one or more domain controllers in a forest.
Query and index mechanism. Active Directory is designed to provide information to queries about directory objects from both users and programs. Administrators and users can easily search for and find information in the directory by using the Search command on the Start menu. Client programs can access information in Active Directory by using Active Directory Service Interfaces (ADSI).
Replication service. Except for very small networks, directory data must reside in more than one place on the network to be equally useful to all users. Through the automatic process of replication, the Active Directory service maintains copies, or replicas, of directory data on each domain controller. Active Directory replication uses a multimaster replication model. With multimaster replication, you can make directory changes at any domain controller, not just at a designated primary domain controller, and your changes will be replicated to all other relevant domain controllers.
Client software. Computers running Windows 95, Windows 98, and Windows NT Workstation 4.0 can access many of the Active Directory features available on Windows 2000 Professional or Windows XP Professional by running the Active Directory client software. To client computers not running Active Directory client software, the directory will appear just like a Windows NT directory.
