ntdsutil을 통한 orphaned Domain 삭제 실패시 조치사항(dcpromo /forceremoval)

[Explanation]

더이상 사용하지 않는(orphanded) Domain을 삭제하기 위해서 우선 dcpromo를 진행하여 진행하려고 하였지만 PDC와 CDC간의 통신이 원활하지 않아서 정상적인 수행이 되지 않았다. 에러는 아래와 같이 'Logon Failure : The target account name is incorrect'

그래서 ntdsutil을 실행하여 재시도하였지만 중간에 'To properly remove the requested server from Active Directory Domain Services, please connect to a server in the domain Domain11.Contoso.com'오류가 발생하였다. 관련해서 구글링을 하여 다음 링크를 통해서 'dcpromo /forceremoval'에 대해 알 수 있었다.
