We mentioned above to remove the domain controller through the normal graphical interface removal method, but sometimes there will be a variety of failures during normal deletion, unable to delete the success of the normal. Or we are preparing to remove the domain controller because of RPC problems, hardware and software compatibility issues, the server itself has been paralyzed or unable to start the network properly, at this time we would like to adopt the normal deletion method is certainly not possible, So this chapter brings us a forced demotion operation by forcing the Ntdsutil tool command to purge the domain controller of this deleted domain from the field network (note: The ntdsutil command does not contact other domain controllers in the domain during the forced removal process. The information in the domain is not deleted, so we do not have to worry about deleting the domain controller information in the "Active Directory Users and Computers" console, as well as the domain controller in the Controllers container, as you normally would when you remove the DCs.

Note: This operation is performed on any one of the domain controller servers.
