Step-By-Step: Manually Removing A Domain Controller Server 

 

Use of DCPROMO is still the proper way to remove a DC server in an Active Directory infrastructure. Certain situations, such as server crash or failure of the DCPROMO option, require manual removal of the DC from the system by cleaning up the server’s metadata. The following detailed steps will help you accomplish this:

Step 1: Removing metadata via Active Directory Users and Computers

  1. Log in to DC server as Domain/Enterprise administrator and navigate to Server Manager > Tools > Active Directory Users and Computers
     
  2. Expand the Domain > Domain Controllers 

     

  3. Right click on the Domain Controller you need to manually remove and click Delete
