Active Directory Recycle Bin Recovery
Let’s begin this section with a very clear statement: If you need to recover a deleted Active Directory object and the Active Directory Recycle Bin was not enabled before the object was deleted, skip this section and proceed to the "Active Directory Authoritative Restore" section.
Active Directory Authoritative Restore
When Active Directory has been modified and needs to be restored to a previous state, and this rollback needs to be replicated to all domain controllers in the domain and possibly the forest, an authoritative restore of Active Directory is required. An authoritative restore of Active Directory can include the entire Active Directory database, a single object, or a container, such as an organizational unit including all objects previously stored within the container. To perform an authoritative restore of Active Directory, perform the System State restore of a domain controller.
