Why should i bring a standalone system into a domain system Offline#
It is permanently offline and can no longer be removed using the removal wizard. Since this is not an option in our case, we select Delete this Domain Controller anyway. The next prompt warns that you should remove a domain controller using the Remove Roles and Features Wizard. If you receive an "Access Denied" or similar permission error when running Move-ADDirectoryServerOperationMasterRole, ensure that your user is a member the Enterprise Admins and Schema Admins group and that you are running PowerShell as Administrator.įrom a working DC in the forest, open Active Directory Users and Computers, navigate to the Domain Controllers container, right-click on the non-functional domain controller and click Delete.Ĭlick the Yes button to confirm deletion. Move-ADDirectoryServerOperationMasterRole ` We add the -Force parameter to seize the roles. Use the Move-ADDirectoryServerOperationMasterRole cmdlet to transfer the roles to a working domain controller. Once the roles have been seized, the old domain controller should not be reconnected to the network, even if it has been restored or recovered. If the FSMO roles are held on a working domain controller in the forest, you can move on to the next section.īefore seizing FSMO roles, you must be absolutely sure that the domain controller currently holding the FSMO roles is never coming back online. If the non-functional domain controller was holding the FSMO roles, we need to seize, or force-transfer, them to a working domain controller. Run netdom query fsmo on a working domain controller in the forest. Instructionsīefore we start cleaning up, we need to make sure that the offline domain controller was not holding the Flexible Single Master Operation (FSMO) roles.
Since the original domain controller is gone, we'll need to manually remove it from Active Directory.
In this scenario, the domain controller is gone for good, but the remaining domain controllers are still attempting to replicate with the offline server.Īside from the replication errors that will fill the event logs of the remaining, functional, domain controllers, this situation can cause authentication and DNS lookup failures for members of the domain. We see this one a lot: a domain controller that either crashed or was uncleanly demoted, but never removed from the Active Directory forest.
