What is a Directory Service?
A directory service provides a place to store information about network-based entities, such as applications, files, printers, and people. It provides a consistent way to name, describe, locate, access, manage and secure information about these individual resources.
A directory service acts as the main switchboard of the network operating system.

Why Have a Directory Service?
Simplifies management
Strengthens security
Extends interoperability

What is Active Directory?
Active Directory is an essential and inseparable part of the Windows 2000 network architecture that improves on the domain architecture of the Windows NT 4.0 operating system to provide a directory service designed for distributed networking environments.
In addition, Active Directory acts as the central authority for network security, letting the operating system readily verify a user’s identity and control his or her access to network resources

How Does Active Directory Work?
Active Directory lets organizations store information in a hierarchical, object-oriented fashion, and provides multi-master replication to support distributed network environments.

Hierarchical Organization
Active directory organizes information hierarchically to ease network use and management.

Object-oriented Storage
Active Directory objects and attributes are protected by access control lists

Multi-Master Replication
To provide high performance, availability, and flexibility in distributed environments, the Active Directory uses multi-master replication.

What are the Benefits of Active Directory ?
It simplifies management tasks It strengthens network security It makes use of existing systems
through interoperability

Conclusion Active Directory services within Windows 2000 provide
a focal point for managing and securing Windows user accounts, clients, servers, and applications.
In addition, Active Directory is designed to integrate with the non-Windows directories within existing systems, applications, and devices to provide a single place and a consistent way of managing an entire network infrastructure.

Conclusion
In this way, Active Directory increases the value of an organization’s existing investments and lowers the overall costs of computing by reducing the number of places where administrators need to manage directory information.
