Gracefully restart AD domain controllers and keep FSMO role assignment unchanged

    Question

  • Hi There,

    We have an AD domain setup with a total of eight domain controllers. 

    Currently Schema master, Domain naming master, PDC, Infrastructure master roles are assigned to a particular DC while RID Pool manager is assigned to a different DC. We'd like to restart the AD domain controllers (as part of maintenance) gracefully while keeping the role assigned unchanged. Could you please let us know what is the appropriate procedure to restart the Domain controllers?

    Thanks in advance for your help.

    Vicky

  • Hi,

    FSMO roles aren't moved when restarting domain controllers. You can restart them one by one without any issues.

  • When you need to transfer FSMO roles?
    When you upgrade a current domain controller (FSMO role owner) to a new hardware server transferring the FSMO roles to the new DC step is required to work Active Directory without any problem.  

    If the FSMO role owner is no longer exist, you need to seize the FSMO roles to healthy DC, that is the reason to have at least 2 DCs in domain with DNS and GC role installed.

  • As already mentioned, an FSMO roles transfer is not triggered by stopping / starting a DC. If your maintenance will take long time to finish, it is advised to transfer the FSMO roles to another DC or you may expect the failures described here: http://archive.oreilly.com/pub/a/windows/2004/06/15/fsmo.html
