The Windows Server 2003 Family Use for Web servers Use for small businesses and departments as domain controllers and member servers Use for medium and large organizations as application servers and domain controllers, and for clustering Use for mission-critical solutions for databases, enterprise resource planning software, high-volume real-time transaction processing, and server consolidation

Windows Server 2003 Cluster Private Network Cluster Node 1 Cluster Node 2 RAID disk sets Multi-initiator SCSI or SCSI over Fiber Channel

Hardware Requirements for an Windows Server 2003 Cluster To use a cluster, you must have: Two or more nodes Drives in each node from which operating system starts A separate mass-storage controller for shared disk A shared disk Two network adapters in each node Two or more nodes Drives in each node from which operating system starts A separate mass-storage controller for shared disk A shared disk Two network adapters in each node Node 2 Node 1 Local Disk Shared Disk Local Disk C: Disk Network Adapter

The Workgroup Model

Domain Model (Windows NT 4.0) Administration and Security BDC Windows 2000 Server Windows NT Workstation Windows XP Professional BDC PDC Directory Database Directory Database Copied Directory Database Copied Directory Database Copied Directory Database Copied Directory Database

Server Role Primary Domain Controller –Maintains master copy of directory database –Validates users Backup Domain Controller –Contains copy of directory database –Validates users Stand-Alone or Member Server –Acts as file, print, and application server

Domain Model (Windows 2000)

Domains A Domain Is a Security Boundary –A domain administrator can administer only within the domain, unless explicitly granted administration rights in other domains A Domain Is a Unit of Replication –Domain controllers in a domain participate in replication and contain a complete copy of the directory information for their domain

What Is a Schema? A forest-wide definition of object classes and attributes that can be extended Schema changes can be redefined or deactivated Examples of object class User Computer Printer Examples of attributes accountExpires department distinguishedName directReports dNSHostName operatingSystem repsFrom repsTo firstName lastName
