Transferring and Seizing operations roles in Active Directory
Seize the Operations Master Role
You can use the Ntdsutil.exe command-line tool to transfer and seize any operations master (also known as flexible single master operations or FSMO) role.
You must use Ntdsutil.exe to seize the schema operations master, domain naming operations master, and relative ID (RID) operations master roles. When you use Ntdsutil.exe to seize an operations master role, the tool first attempts a transfer from the current role owner.
If the current role owner is not available, the tool seizes the role.
When you use Ntdsutil.exe to seize an operations master role, the procedure is nearly identical for all roles. There is a minor change in the command syntax for versions of Ntdsutil.exe that run on Windows Server 2008 and Windows Server 2008 R2, as noted in the following table.
For more information about using Ntdsutil.exe, type ? at the ntdsutil: command prompt.
Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure.
