Answer #1
"Active Directory is the directory service used in Windows 2000 Server and is the foundation of Windows 2000 distributed networks."

The core of Active Directory is a combination of an LDAP server and MIT Kerberos 5 KDC running on a Windows 2000 server acting as a domain controller that work as a unit to provide authentication ("Who are you?") and authorization ("What are you allowed to do?") information within a group of interlinked systems.

Above and beyond that, the LDAP "face" of this structure behaves as an enterprise-wide distributed database that not only contains Windows-specific information but can be extended to incorporate user-defined data as well.

The AD is held together by DNS, which is used not only to locate specific machines within the AD but also to locate which functions of the AD are running on which domain controllers.

Answer #3
An active directory is a directory structure used on Microsoft Windows based computers and servers to store information and data about networks and domains. It is primarily used for online information and was originally created in 1996 and first used with Windows 2000.

An active directory (sometimes referred to as an AD) does a variety of functions including the ability to provide information on objects, helps organize these objects for easy retrieval and access, allows access by end users and administrators and allows the administrator to set security up for the directory.

An active directory can be defined as a hierarchical structure and this structure is usually broken up into three main categories, the resources which might include hardware such as printers, services for end users such as web email servers and objects which are the main functions of the domain and network.

Active Directory is Microsoft's trademarked directory service, an integral part of the Windows 2000 architecture. Like other directory services, such as Novell Directory Services (NDS), Active Directory is a centralized and standardized system that automates network management of user data, security, and distributed resources, and enables interoperation with other directories. Active Directory is designed especially for distributed networking environments.
