Creating domain controllers is fun, but leveraging all of them is key to implementing a responsive and highly-available Active Directory. Therefore, we'll focus on the differences between domain controllers in terms of Flexible Single Master Operations (FSMO) roles and global catalog configuration. There's a reason why the following quote, inspired by George Orwell's Animal Farm, is popular among Active Directory admins:
"All domain controllers are equal, but some domain controllers are more equal than others."
The following recipes will be covered in this chapter:
- Querying FSMO role placement
- Transferring FSMO roles
- Seizing FSMO roles
- Configuring the Primary Domain Controller emulator to synchronize time with a reliable source
- Managing time synchronization for virtual domain controllers
- Managing global catalogs...
