Overview
This lecture introduces Active Directory as the core feature of distributed systems in Microsoft Windows 2000, outlining its architecture and key operational components for network administrators.
Introduction to Active Directory
- Active Directory is a central directory service in Windows 2000 for managing network resources and users.
- It serves as the foundation for distributed systems within Microsoft’s enterprise environments.
- Knowledge of Active Directory is important for implementing and troubleshooting directory services.
Core Components and Functions
- Active Directory organizes directory information logically and physically using its structured architecture.
- Key tasks include storing data about objects on the network, such as users, groups, and devices.
- It enables name resolution, allowing users and computers to locate resources across the network.
- The schema defines types of objects and attributes stored in Active Directory.
- Service publication allows services to be advertised and located using Active Directory.
- Replication ensures directory data is consistent across multiple domain controllers.
Administration, Operations & Maintenance
- Flexible Single-Master Operations (FSMO) manage specific roles to prevent conflicts in directory changes.
- Performance monitoring is essential to maintain Active Directory health and reliability.
- Backup and restore procedures are critical for disaster recovery.
- Diagnostics and troubleshooting tools support the identification and resolution of directory service issues.
Key Terms & Definitions
- Active Directory — a directory service for Windows networks, centralizing management of users, computers, and resources.
- Schema — the set of rules that defines objects and their attributes in Active Directory.
- Replication — the process of copying directory data between domain controllers to maintain consistency.
- Flexible Single-Master Operations (FSMO) — specialized roles assigned to domain controllers to handle unique directory operations.
Action Items / Next Steps
- Review sections on logical structure, data storage, replication, and schema for deeper understanding.
- Practice using backup, restore, and troubleshooting tools in a test environment.
