Contents Exit focus mode. Therefore, there is only one schema master and one domain naming master per forest. Right-click the selected Domain Object in the top-left pane, and then click Operations Masters. Click the Infrastructure tab to view the server holding the Infrastructure master role. Right-click Active Directory Schema in the top-left pane, and then click Operations Masters to view the server holding the schema master role.
Is this page helpful? Yes No. One method of transferring FSMO roles is to demote the domain controller that owns the roles. When a domain controller is demoted it will attempt to transfer any FSMO roles it owns to suitable domain controllers in the same site.
Domain-level roles can only be transferred to domain controllers in the same domain, but enterprise-level roles can be transferred to any suitable domain controller in the forest. While there are rules that govern how the domain controller being demoted will decide where to transfer its FSMO roles, there is no way to directly control where its FSMO roles will be transferred.
During a manual transfer, the source domain controller will synchronize with the target domain controller before transferring the role.
If the is not among the available Management Console snap-ins, it will need to be registered. To register the Active Directory Schema Management Console, open an elevated command prompt, type regsvr32 schmmgmt.
The roles being transferred are specified using the -OperationMasterRole parameter:. Transferring FSMO roles requires that both the source domain controller and the target domain controllers be online and functional.
The reintroduction of a FSMO role owner following the seizure of its roles can cause significant damage to the domain or the forest. Using the -Force parameter will direct the cmdlet to attempt an FSMO role transfer and then to seize the roles if the transfer attempt fails.
As each role only exists once in a forest or domain, it is important to understand not only the location of each FSMO role owner and the responsibilities of each FSMO role but also the operational impact introduced by the unavailability of a FSMO role-owning domain controller. Such information is valuable in situations where a domain controller is unavailable, whether due to unanticipated events or while scheduling and performing planned upgrades and maintenance.

Type q , and then press Enter to quit the Ntdsutil utility. If it is possible, and if you are able to transfer the roles instead of seizing them, fix the previous role holder. If you cannot fix the previous role holder, or if you seized the roles, remove the previous role holder from the domain.
If you plan to use the repaired computer as a DC, we recommend that you rebuild the computer into a DC from scratch instead of restoring the DC from a backup.
The restoration process rebuilds the DC as a role holder again. On another DC in the forest, use Ntdsutil to remove the metadata for the former role holder. For more information, see To clean up server metadata by using Ntdsutil. After you clean up the metadata, you can repromote the computer to a DC, and transfer a role back to it. When part of a domain or forest cannot communicate with the rest of the domain or forest for an extended time, the isolated sections of domain or forest are known as replication islands.
DCs in one island cannot replicate with the DCs in other islands. Over multiple replication cycles, the replication islands fall out of sync. If each island has its own FSMO role holders, you may have problems when you restore communication between the islands.
In most cases, you can take advantage of the initial replication requirement as described in this article to weed out duplicate role holders. A restarted role holder should relinquish the role if it detects a duplicate role-holder. You may encounter circumstances that this behavior does not resolve.
In such cases, the information in this section may be helpful. The following table identifies the FMSO roles that can cause problems if a forest or domain has multiple role-holders for that role:. These role holders do not persist operational data.
The Netdom tool is built into Windows Server and up. On any domain controller open the command prompt. On Windows server click the start button and type cmd, windows will search and return the command prompt. Using Powershell will require two lines of code, one to return the forest roles and another to return the domain roles.
