Transfer the Domain-Level Operations Master Roles
Applies To: Windows Server 2008, Windows Server 2008 R2
You can use this procedure to transfer the following three domain-level operations master (also known as flexible single master operations or FSMO) roles:
Primary domain controller (PDC) emulator operations master
Relative ID (RID) operations master
Infrastructure operations master
You might want to transfer a domain-level operations master role if the domain controller that currently hosts the role is inadequate, has failed, or is being decommissioned. You can transfer all domain roles by using the Active Directory Users and Computers snap-in.
You perform these procedures by using a Microsoft Management Console (MMC) snap-in, although you can also transfer these roles by using Ntdsutil.exe. For information about using Ntdsutil.exe to transfer the operations master roles, see Ntdsutil (http://go.microsoft.com/fwlink/?LinkID=120970.) For information about the ntdsutil command, can also type ? at the Ntdsutil.exe command prompt.
Before you perform this procedure, you must identify the domain controller to which you will transfer the operations master role.
Membership in Domain 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 (http://go.microsoft.com/fwlink/?LinkId=83477).
To transfer a domain-level operations master role
Open Active Directory Users and Computers: On the Start menu, point to Administrative Tools, and then click Active Directory Users and Computers. If the User Account Control dialog box appears, provide Domain Admins credentials, if required, and then click Continue.
At the top of the console tree, right-click Active Directory Users and Computers, and then click Change Active Directory Domain Controller.
Ensure that the correct domain name is entered in Look in this domain.
The available domain controllers from this domain are listed.
In the Name column, click the name of the domain controller to which you want to transfer the role, and then click OK.
At the top of the console tree, right-click Active Directory Users and Computers, click All Tasks, and then click Operations Masters.
The name of the current operations master role holder appears in the Operations master box. The name of the domain controller to which you want to transfer the role appears in the lower box.
Click the tab for the operations master role that you want to transfer: RID, PDC, or Infrastructure. Verify the computer names that appear, and then click Change. Click Yes to transfer the role, and then click OK.
Repeat steps 5 and 6 for each role that you want to transfer.
