Microsoft have updated the must read Active Directory document on Active Directory Forest Recovery.
“The guide contains best-practice recommendations for recovering an Active Directory forest if forest-wide failure renders all domain controllers in the forest incapable of functioning normally. The steps, which you must customize for your particular environment, describe how to recover the entire Active Directory forest to a point in time before the critical malfunction. They also ensure that none of the restored domain controllers replicate from a domain controller with potentially dangerous data.
The steps in this guide apply to Active Directory forests where the domain controllers run Microsoft® Windows Server 2012, Windows Server 2008 R2, Windows Server 2008, and Windows Server 2003 operating systems.”
Please ignore the fact that the document is titled “Windows Server 2008: Planning for Active Directory Forest Recovery” it covers all supported versions of Windows Server that can run Active Directory.
April 2013 Update.
