Presentation Transcript

  1. Active Directory Boundaries - Purpose • Replication Boundaries • Security Boundaries

  2. Active Directory Boundaries - Types • Geographic vs Organizational • Contiguous vs Discontigous namespace • i.e. oldcompany1.newcompany.com and oldcompany2.newcompany.com are 2 contiguous namespaces

  3. Prestaging • forestprep and domainprep • Removal

  4. Removing Domains or Trees • ADMT pruning/grafting • ADMTv3.1

  5. Functional Levels • Viewing • Raising • Interoperability • UPN – User Principal Name

  6. Simplifying Logon • Each user • Has a unique down-level logon name • Can have multiple friendly UPN's

  7. Trust Basics • Trusts allow communication between the boundaries of domains and forests • 1 way Trust • 2 way Trust

  8. Transitive Trusts • Extend permissions across multiple domains • Automatically created as new domain joins a tree or new child is created

  9. Forest Trusts • Forest wide • Selective authentication

  10. External Trusts • Non-Transitive • NT4.0 or Kerebos compatible

  11. Shortcut Trust • Transitive • Speeds up authentication and authorization

  12. Identity • Security Identification (SID) filtering

  13. Create Sites • Balance service delivered to all locations. • Inventory the number of users at each site • Inventory the types of WAN links

  14. Create AD Subnets • Associate subnets with the site location that has the closest DC

  15. Configure Site Links • Site Links = WAN links • Star vs Mesh

  16. Associating Link Costs • Cost = Speed/Availability of WAN

  17. Configure Infrastructure • Manually link Operational Masters with their backup servers

  18. Global Catalog Servers • Deploy Global Catalog servers at each site when possible

  19. Replication • Each domain can have its own replication topology and schedule • Different events have different priorities to trigger replication

  20. DFS • DFS – Distributed File System • Method for synchronizing shared folders

  21. DFS • DFS – Distributed File System • Method for synchronizing shared folders • Conflict and Deleted folder • Good for application distribution or other read-only data

  22. Replication - Automatic • Knowledge Consistency Checker (KCC) • Bridgehead Server • Intersite Topology Generator

  23. Replication - Automatic • Knowledge Consistency Checker (KCC) • Bridgehead Server • Intersite Topology Generator • Scheduling • IP and SMTP protocols

  24. Replication - Manual • Designate a specific bridgehead server • Make a one way replication partnership • Manually force replication after making changes to AD

  25. Global Catalog Server • DC that contains information about other Domains

  26. Promotion • Use the AD snap-in Sites and Services • Partial Attribute Set

  27. Alternate Methods • UGMC – Universal Group Membership Caching

  28. Domain Operations Masters • PDC emulator • Relative ID (RID) • Infrastructure

  29. Forest Operations Masters • Schema Master • Domain Naming

  30. Operations Master • Seize vs Transfer • Backup • Placement

  31. Schema Master • Schema can be extended with various tools • Placement should be on a Global Catalog • Time Service is important for successful upgrades
