Deleting a domain controller from domain RRS feed

  • Question

  • Hi All,

    I have 7 domain controllers in a domain in which one domain controller is really old and we wanted to decommission it. The Domain controller server is turned off & now when we do nslookup it gives timeout.

    We can still see the old domain controller in active directory users and computers. I think this domain controller is not deleted properly. This was the primary domain controller before so, we transferred the FSMO role & then decommissioned the old server.

    Do, we need to remove it from domain. What's the process for that.

    Please, help.

    Thanks,

    Pranay.
