The Workgroup Model
Domain Model (Windows NT 4. 0) PDC Copied Directory Database BDC Copied Directory Database Administration and Security Windows 2000 Server Windows XP Professional Windows NT Workstation
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
DNS and Active Directory Namespaces DNS Namespace Internet “. ” (DNS root domain) Active Directory Namespace com. microsoft. com training sales training. microsoft. computer 1 sales. microsoft. com = DNS node (domain or computer) = Active Directory domain
Logical Structure • • Domains Organizational Units Trees and Forests Schema Domain Tree Domain Forest Domain Tree Domain OU

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 account. Expires department distinguished. Name direct. Reports d. NSHost. Name operating. System reps. From reps. To first. Name last. Name
Physical Structure • Sites • Domain Controllers Domain Site

將 NT 4. 0 Domain 順利升級成 AD • 在 Windows NT 4. 0 Domain 中加裝一台 BDC – 新機的硬體須能支持 Windows Server 2003 • • • 暫時 Shutdown 原本的 PDC 將新的 BDC 強迫升級成 PDC 安裝 Windows NT 4. 0 SP 6 以上 將新的 PDC 升級成 Windows Server 2003 如果有任何意外，只需將新的 PDC Shutdown， 再將舊的 PDC 重新開機即可！
