This system is a Domain Controller but the Active Directory service is stopped. You can not perform the operation unless the Active Directory service is running.
The Active Directory service must be running when you back up or restore the system state or operate on Active Directory objects. When the Active Directory service is running, it can be in online state or in offline state. When you query or restore Active Directory objects, or back up the system state, the Active Directory service must be online. When you restore the system state, the Active Directory service must be offline (but not stopped).
Processing stopped.
If you are querying or a restoring the Active Directory objects or backing up the system state, put the Active Directory service in online state by starting the Active Directory service. If you are restoring the system state, put the Active Directory service in offline state by rebooting to the Active Directory Restore Mode. When the Active Directory service is in the appropriate state, retry the operation.
