rebooting server time out of sync RRS feed

  • Question

  • whenever I reboot my server the time goes out of sync. The server is in a remote time zone but it has its own dc so the time sync should be syncing with that dc. I am not sure where its getting its time from after a reboot

  • The Windows time service follows the domain/forest hierarchy, and works out-of-the box without requiring changes, alterations or anything else. The hierarchy is show in the following diagram taken from


    More info on the time service, and how to troubleshoot it can be found here:

    Configuring the Windows Time Service for Windows Server, explanation of the time service hierarchy, and more


    If you can describe your domain structure, (single domain, multiple domains, etc), DNS structure, etc, it would be helpful to diagnose the problem.

    Also, just to eliminate any configuration issues, make sure that all machines are only using the internal DNS server. If using an external DNS server, such as an ISP's, the router, or any other that does not host the internal AD zone for Active Directory, otherwise this will cause issues, too.

    In addition, has anything been changed or attempted to alter the default time service settings on any machine?

    Any Event log errors regarding the time service on any machine?

    Is the BIOS battery intact on this server?

    Time zones don't really make a difference since all time is relevant to Zulu (Greenwich) time.
