Transfer the Domain Naming Master
Applies To: Windows Server 2008, Windows Server 2008 R2
You can use this procedure to transfer the domain naming operations master role if the domain controller that currently hosts the role is inadequate, has failed, or is being decommissioned. The domain naming 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 domain naming operations master role.
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 also type ? at the Ntdsutil.exe command prompt.
Membership in Enterprise 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).
