Server 2012 R2 Domain Controller stops accepting log in

    Question

  • I am having a strange random issue with the main domain controller not accepting log in from workstations and the DNS stops resolving, but after a reboot everything works again. This mainly occurs after a windows update as been applied.

    Any ideas what would cause the domain controller to stop authenticating users?

  • Hi,
    In my experience on windows update before, some patches make server be hang or server was crashed in the process of rebooting to take effect of updates. To avoid this case. I updated the domain controller on weekends (non-business day) and scheduled a task to reboot domain controller again before weekdays (business day) to make sure that server was fully rebooted. Just my suggestion on the windows updates based on my experience.
