Metadata cleanup is performed when a domain controller is forcibly removed from Active Directory Domain Services (AD DS) as due to a hardware failureof the server, which leads to the decommissioning of hosting, and due to the fact that the server may be unreasonably downgraded in the rating. Metadata cleanup removes stagnant data and ADDS records, most of which are identified as domain operators for the replication system. It simultaneously transfers or maintains all of the Flexible Authorized User Management (FSMO) roles that have been retired by a particular domain controller.
Purge metadata can also be done in one of the following ways:
|If you’re getting all the “Access Denied” errors when someone uses one of these metadata cleanup methods, make sure the experts say the computer object and NTDS object settings for the controlled domain aren’t protected from accidental deletion. To make sure To do this, right-click the Drive object or the NTDS Settings toy, click Properties, click Object, and uncheck Protect object from accidental deletion.
In the Active Directory Users and Computers section, if you click View and then Advanced Features, the Object Assignment tab appears.
These procedures require a minimum membership of domain administrators or domain equivalent.
Applies to: Windows Server ’08, Windows Server 2008 R2, Windows Server 2012
If you use Remote Server Administration Tools (RSAT) or the Active Directory Users and Computers Console (Dsa.msc) to remove a failed domain controller computer subscription from the storage unit (OR ) of the domain controllers organization, a cleanup occurs. server metadata is generated automatically. Previously, you had to perform a separate metadata cleanup process.
You can also use the services and Active Directory Sites Console (Dssite.msc) which can remove the domain controller computer’s credit account, which also completes the cleanup quicklymetadata. However, Active Directory Sites and Services will not automatically align metadata unless you and your family members remove the Computer Account NTDS Settings entry in Dssite.msc.
If you’re using Windows Server 2008, Windows Server 2008 R2, or RSAT versions of Dsa of.msc or Dssite.You msc, you can automatically purge metadata associated with domain controllers that are running earlier versions of Windows operating systems.
- Open Directory Users and Computers (dsa.msc).
- Find the domain controller whose metadata you want to purge (it turns out to be in the domain controller OU) and finally click delete

- You cannot change the range of this controller. If you want to be able to move the role to an unusual domain controller, you must move the regular role after you complete the metadata server cleanup.
- Open Active Directory Sites and Services
- If customers specified replication partners when setting up this procedure, and someone is not associated with the remote controller’s domain replication partner whose metadata you are clearing, click the button to the right of Active Directory Users and Computers
, and then click Change Controller domain. Click the name of the domain control whose metadata you want to retrieve, and then click OK.
- Deploy the website of the exact domain controller thatwas forcibly evicted, expand Servers, expand that controller’s domain name, right-click the exact NTDS Settings object (if the NTDS Settings object is missing, it was actually deleted when we removed the domain controller from AD) and click Delete.
