Below is few methods to cleanup metadata. 


#Using GUI:

  1. To remove the failed server object from the domain controller’s container
  2. Go to Start à Admin tools à Active Directory Users and Computers
  3. In Active Directory Users and Computers, expand the ‘Domain Controllers’ OU.
  4. Delete the computer object associated with the failed domain controller.
  5. If you get a prompt saying you want to delete the server object without performing a DCPROMO operation be sure to check “This DC is permanently offline…” before clicking on the delete button
  6. Windows will prompt you again like you don’t know what you are doing, so go ahead and click yes on the next prompt if you get it.


Note: Metadata cleanup is automated with windows server 2008. We just need to delete the computer object from the Domain Controllers OU using ADUC from a Windows Server 2008 machine and the metadata cleanup process occurs automatically.




#Using ntdsutil:

  8. Type select domain <number>, where <number> is the number corresponding to the domain in which the failed server was located. Press Enter.
  9. Type list sites and press Enter.
  10. Type select site <number>, where <number> refers to the number of the site in which the domain controller was a member. Press Enter. We will use site 0.
  11. Type list servers in site and press Enter. This will list all servers in that site with a corresponding integer.
