How to delete a domain controller

DeleteDomain ControllerIs what we sometimes have to do, that is, deleteActive DirectorySo how to delete Active Directory from the domain controller?

Note:

When you downgrade a domain controller, if it is not the last domain controller in the domain, it performs the last copy and transfers the role to another domain controller. As part of the downgrade process, the Dcpromo utility deletes configuration data for this domain controller from Active Directory. This data is in the form of an "NTDS Settings" object, which exists as a sub-object of the server object in "Active Directory site and Service Manager. After the domain controller is downgraded, it no longer has available Active Directory Information and uses the "Security Account Manager" (SAM) database to obtain local database information. If the domain controller is a Global Catalog domain controller, this role will not be transferred to another domain controller. In this case, you must manually select the check box in "Active Directory site and Service Manager" to allow another domain controller to take over this role.

If the degradation process fails to be completed for some reason, you must manually delete the metadata from the directory. Use the Ntdsutil.exe utility to manually delete the "NTDS Settings" object.
