FSMO Roles

While most DCs are equal (Multi-Master Replication), there are 5 specific roles called Flexible Single Master Operations (FSMO) roles that must be unique.

  1. Schema Master: Controls updates to the schema (the definition of object types).
  2. Domain Naming Master: Controls the addition/removal of domains in the forest.
  3. PDC Emulator: Handles time synchronization and password changes for older clients.
  4. RID Master: Allocates pools of unique IDs (RIDs) to DCs to create new objects.
  5. Infrastructure Master: Updates references to objects in other domains.
