Unable to access any mapped drives from our Windows 2021 Standard Server

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):

The processing of group Policy failed. Windows could not authenticate to the active directory service on a domain controller. (LDAP Bind function call failed).

Invalid credentials

I am really stuck!
It's like AD/DNS aren't working.
