Operations Master Roles Assignment

  • Article

Active Directory Domain Services (AD DS) defines five Operations Master Roles (also known as flexible single master operations or FSMO) that are used to perform specialized tasks. The following operations master roles are defined in AD DS:

  • Schema master
  • Domain naming master
  • RID master
  • PDC master
  • Infrastructure master

The PDC master and Domain naming master roles must be assigned to the Management Server to comply with the licensing terms for Windows EBS. If these roles are not assigned, the Management Server automatically shuts down 28 days after the condition is first detected, unless corrective action is taken.
