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. Additionally, the Infrastructure master does not make changes often.
Therefore, if multiple islands have these role holders, you can reintegrate the islands without causing long-term issues. Each island that has one of these role holders could have duplicate and conflicting schema objects, domains, or RID pools by the time that you restore replication. Before you reintegrate islands, determine which role holders to keep. Remove any duplicate Schema masters, Domain Naming masters, and RID masters by following the repair, removal, and cleanup procedures that are mentioned in this article.

Important AD FS operations fail if they require a role holder and if the newly started role holder is, in fact, the role holder and it does not receive inbound replication.
Note We recommend that you only seize all roles when the previous role holder is not returning to the domain. If FSMO roles have to be seized in forest recovery scenarios, see step 5 in Perform initial recovery under the Restore the first writeable domain controller in each domain section.
After a role transfer or seizure, the new role holder does not act immediately. Instead, the new role holder behaves like a restarted role holder and waits for its copy of the naming context for the role such as the domain partition to complete a successful inbound replication cycle. This replication requirement helps make sure that the new role holder is as up to date as possible before it takes action. It also limits the window of opportunity for errors. This window includes only changes that the previous role holder did not finish replicating to the other DCs before it went offline.
Caution Do not put the Infrastructure master role on the same DC as the global catalog server. As shown in Figure Schema Master role as seen in Active Directory Schema snap-in. Some command-line utilities allow you to identify the role holders.
The first, netdom , will show you all of the role holders at the same time. The second, dsquery, will allow you find individual roles when you ask for them. The DCDiag utility will show you all of the roles. The final utility is from the Windows Server resource kit , dumpfsmos.
Of course, you would replace zygort. This will return a list of all of the role holders. The syntax for this command is:. Of course, you would want to replace zygort. If you are demoting a role holder, be sure to transfer the role to another domain controller, preferably the domain controller you have designated as the standby role holder. Doing so will guarantee that you are transferring the role to the appropriate domain controller instead of allowing dcpromo to choose another domain controller on its own.
Remember: it is always better to have control over these things than to allow chance to control your organization. If you are taking a domain controller offline permanently, whether it is a role holder or not, you should demote it so that the references to the domain controller are removed from Active Directory. Transferring the role to another domain controller is a very simple process.
Using the snap-ins that we discussed in the "Identifying the Current Role Holder" section, you can simply connect to the domain controller that you want to be the new role holder, choose the Operations Master option to view the role holder, and click Change. Namely, the event viewer is not going to tell you that you have a problem resolving names.
Logic has to tell you there is a name resolution issue. In this case, the thing that indicates that you might have a DNS problem is this:. Thank you all so much for your advice. I apologize for my late response. The office has me moving. I assume this may have been one of my issues. I immediately, clicked edit and then resolve. However I am still having a few GPO issues much like the one below.
The image itself is clear cut however, If I click " Ok " and the permissions gets changed, So far I have noticed that some one the GPO has stopped applying. Any suggestions? Thank you for your response. I posted a general response but it seems it was flagged for moderation. I have changed a few and noticed some are still working and some have stopped.
One of them that has stopped is my printer GPO i have tried to recreate it but nothing. To continue this discussion, please ask a new question.
