We have a single Physical 2016 Standard server on a small site with 15 people. The Server restarted last night after installing updates. This morning the office manager called to say nobody could get online. So I tried remoting in but got the message that the domain controller could not be contacted.
Using light Out, I could get to the servers login screen but it says there is no Domain controller available to process the login with my account. I have logged on with the Administrator account and tried to start the Active Directory & DNS services, but active directory starts and stops immediately.
I tried to uninstall the updates, but that failed.
I know the daily backup to an external drive using Windows backup succeed on the previous evening. But I am offsite and would like to see if I can recover without restoring from it.
What would be my best course of action from this point?
