Recovering Active Directory data

Active Directory recovery differs depending on the type of recovery required.

This section considers the following disaster scenarios:

• A domain controller is lost but other domain controllers are still available. See “Recovering a domain controller (other DCs are available)”.
• All domain controllers are lost (or there was only one). See “Recovering a domain controller (no other DCs are available)”.
• The Active Directory database is corrupted and the Active Directory service does not start. See “Restoring the Active Directory database”.
• Certain information is accidentally deleted from Active Directory. See “Restoring accidentally deleted information”.
