  • Directory Service Error ID: 1864 occur daily

    Hi all,

    My Environment is Single Forest Single Domain.
    There have 2 bridgehead Server.
    For Root DC bridgehead A, all the replication DC is work well.
    However bridgehead B, there have 5 DC are pass the tombstone lifetime.

    Recently I check on the Event Viewer -> Directory Service.
    There have an error ID: 1864 is occur daily and same time (Daily 3:30pm).

    Question
    1. May I know why the Event ID 1864 is occur daily at a same time?
    2. Why those error occur at DC have connection site link with Bridgehead A?
    3. Is there any solution to solve this?

      Hi L4NDY,

      I had post the DCDIAG, I understand the in the report shown that there have some DC is pass the tombstone life time.

      Those DC are only under same site with bridgehead B, and there have no site replication to bridgehead A site.

      Now all the DC have site link with bridgehead A receive error per daily basis and same time.

      There have an error ID: 1864 is occur daily and same time (Daily 3:30pm).

      Question
      1. May I know why the Event ID 1864 is occur daily at a same time?
      2. Why those error occur at DC have connection site link with Bridgehead A?
      3. Is there any solution to solve this?

        It looks to me that Domain controllers in the past haven't been demoted gracefully. Do any of these DC still exist: AEID-16AD01, AEID-35AD01, AEID-24AD01, etc there are about half a dozen there? some dating back to 2007?
        If not establish first what you have in there, then check where your FSMO roleholders are, seize if necessary, then do a metadata cleanup.
        The events logged should coincide with the replication schedule and they should go once the metadata cleanup has been completed.

          Hi L4ndy,

          Thanks for your help.

          1. Those DC are still active and needed. The problem now is because those DC already long time didn't done Replication.
          2. FSMO roleholders is AEM-ITD-AD01, the root DC.

          Question.
          1. May I know what should I do if I need those DC?
          Need demote the DC?
          2. Because I'm new, just start learn AD, May I know how to perform metadata cleanup?

            Hi,

            The answer to your question would be:

            1- Troubleshoot AD Replication
            2- Metadata Cleanup
