Decommissioning the old Domain Controller

    Question

  • I was using windows server 2008 32 sp1 Server as DC.

    I added new server as ADC first and then transferred FSMO role to New server Windows server 2008 R2 64 .. made new server DC.

    It is working now...

    what should I do to  decommission old server? need to remove from my entire network..

    Should I perform any cmd or any activity??

  • Hi

     Follow the steps on the article to remove dc from domain;

    https://technet.microsoft.com/en-us/library/cc771844%28v=ws.10%29.aspx?f=255&MSPPError=-2147217396

    But before proccess just take a full backup and verify dc's health,fsmo roles transfered and PDC is healthy,and replication health also.

    run

    - netdom query fsmo ; to check fsmo roles holder

    - dcdiag ; to check dc health

    - repadmin /replsum ; verify replication summary..

  • Hi,
    In addition, after demoting the old domain controller, it is also suggested to clean up its metadata:

  • Hi ,

    1. If the affected DC can be demoted successfully (through command dcpromo or through Server Manager console), just wait for some time until every DC notices this change, and there’s no extra things need to do.
    2. If the affected DC cannot be demoted successfully, perform what we did in our late remote session by follow KB216498 on another good DC.
    Any other method (for example from ADSS console) is not recommended because it’s simple but may not be able to cleanup all the metadata.
