We are looking at the topic of DR at the moment and I would like your expert help in the creation of a DR plan in the event that our PDC somehow goes kaput!

Info: Our PDC holds all FSMO roles We have 3 secondary DC's around our environment

Is there a method to transfer FSMO roles to another DC if we cannot access the PDC?

Regards

There is no immediate impact if your PDC DC goes down. You can plan to manually seize the PDC role from one of the remaining domain controllers. The process is descrbed well here https://www.petri.com/seizing_fsmo_roles

  • Many many thanks, this will be a great starting point to look at. – Z Holt Feb 05 '16 at 14:11
  • Would it be easier/quicker to restore the DC from a VM backup (perhaps 3 days old at the time) – Z Holt Feb 05 '16 at 14:23
  • Your concern with that approach should be replication issues. 3 days should be Ok but longer periods of time risk USN rollback. I don't have any direct experience recovering from a snapshot. https://windorks.wordpress.com/2014/07/25/ad-replication-issues-usn-rollback-and-the-invocation-id/ – Eric Feb 05 '16 at 15:34

You can't transfer, but you can seize them:
