What is AD FSMO roles?

Question

Accepted Answer

AD FSMO roles are the 5 special roles in Active Directory that are responsible for managing various aspects of the domain.

There are 5 FSMO roles: Schema Master, Domain Naming Master, RID Master, PDC Emulator, and Infrastructure Master.
Schema Master: responsible for making changes to the Active Directory schema.
Domain Naming Master: responsible for adding or removing domains in the forest.
RID Master: responsible for allocating RIDs (Relative Identifiers) to domain controllers.
PDC Emulator: responsible for providing backward compatibility for older clients and managing password changes.
Infrastructure Master: responsible for updating group-to-user references within a domain.
Each role can only be held by one domain controller at a time.
If a domain controller holding an FSMO role fails, the role must be transferred to another domain controller.
FSMO roles can be transferred using the Active Directory Users and Computers console or the NTDSUTIL command-line tool.
