DNS Service not starting RRS feed

  • Question

  • I have a DC the is also my DNS server. Recently the DNS service has stopped running and I am not sure why. Both services that it is dependent on have been restarted and I have tried to run it manually. Every time I start it though, it stops automatically. Is there something I've missed or am unaware of?

  • You need to check the logged events in the server event viewer. Please also try to temporary disable security software running on the server and try again. If you are running an AV, please make sure that the exclusions are properly done: https://support.microsoft.com/en-gb/kb/822158

    If this is not the only DC you have and you still do not figure out the cause of the issue, the quickest fix (Assuming that you have another DC/DNS/GC server which is healthy) would be to proceed as the following:

    1. Transfer the FSMO roles from the faulty DC to another DC (I assume here that the faulty DC is the FSMO roles holder)
    2. Demote  the faulty DC
    3. Re-install the faulty DC OS
    4. Promote the re-installed server to be a DC/DNS/GC server and transfer back the FSMO roles

  • Hi JRobTTG,

    I have a DC the is also my DNS server. Recently the DNS service has stopped running and I am not sure why. Both services that it is dependent on have been restarted and I have tried to run it manually. Every time I start it though, it stops automatically. Is there something I've missed or am unaware of?

    Please check if you have installed KB3145216(2008R2), if you have, remove it and try again.

    If you have any third-party antivirus software, please temporary stop it and test again.(e.g. Symantec)

    Please check the DNS role related logs under system event viewer to see if there are any useful information for further assistance.

    Best regards,

  • The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

    This is the only error that I receive when I check the DNS event log. I am trying to see if I can stop the replication process since there is nothing for AD to sync to anyway. As I said before this is the only DC in this domain. I checked for that update/patch as well and it has not been installed.

  • Hi JRobTTG,

    Thanks for your feedback.

    Please check if you have configured AD domain trust relationship on AD Domains and trusts.

    Besides, please check if the following blog is helpful:

    In addition, please check if you have any antivirus software or third-party applications that have lead this issue.

    Best regards,
