At 5:00 am, our 2012 Standard Windows Server Froze up.
I had to perform a cold boot. It looked like it wanted to repair the OS via the widows diagnostic screen, instead it just restarted, after my initial cold boot, and it was back up. I am now logged in locally to the server. Yet no one can gain access to the mapped drives. Yes, I can ping.
I noticed a handful of services are listed as 'Delayed Start' and 'Trigger Start'
I check the event log.
It started here:
06/18/2021 5:02 AM Kernel-General
An I/O operation initiated by the Registry failed unrecoverable. The Registry could not flush hive (file):
Event ID: 6
06/18/2021 8:00 am GroupPolicy (Microsoft-Windows-GroupPolicy)
The processing of group policy failed because of lack of network connectivity to a domain controller
Event ID: 1129
06/18/2021 8:06 am Group Policy
The processing of group Policy failed. Windows could not authenticate to the active directory service on a domain controller. (LDAP Bind function call failed).
Event ID: 1006
I am really stuck!
It's like AD/DNS aren't working.
