Transfer the Schema Master

  • Article

Applies To: Windows Server 2008, Windows Server 2008 R2

You can use this procedure to transfer the schema operations master role if the domain controller that currently hosts the role is inadequate, has failed, or is being decommissioned. The schema master is a forest-wide operations master (also known as flexible single master operations or FSMO) role.

Before you perform this procedure, you must identify the domain controller to which you will transfer the schema operations master role.

Before you can use the Active Directory Schema snap-in for the first time, you must register it with the system. If you have not yet prepared the Active Directory Schema snap-in, see Install the Schema Snap-In before you begin this procedure.

Note

You perform this procedure by using a Microsoft Management Console (MMC) snap-in, although you can also transfer this role by using Ntdsutil.exe. For information about using Ntdsutil.exe to transfer operations master roles, see Ntdsutil (https://go.microsoft.com/fwlink/?LinkId=120970). For information about the ntdsutil command, you can type ? at the Ntdsutil.exe command prompt.

Membership in Schema Admins, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
