Hi all, i have some problems with an AD Server apparently after applying the updates on december 27, 2021.
It is a single AD Server environment, so no replication processes, running on Windows Server 2019.
I have DNS error 4000 and 4007, i cannot open DNS Manager, it returns "Access was denied. Would you like to add it anyways?"
I've tried resetting netdom password with no results, both with kdc service on and off.
Testing the AD Services with dcdiag /fix it returns this, it cannot resolve the IP address cause of the problems mentioned before.
It seems like a loop problem, the DNS Server doesn't work because AD isn't working and vise versa.
Can anyone help me?
Thanks a lot!

@Anonymous please check the third image posted, i've tried with the kdc service on/off and got two different errors
for the network profile, it's getting "Private" now
Try restarting the Network Location Awareness (NLA) service.

Please run;
Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log
repadmin /showrepl >C:\repl.txt
ipconfig /all > C:\dc1.txt
ipconfig /all > C:\dc2.txt
then put unzipped
text files up on OneDrive and share a link.
Might check that all Auto start services have started up, failing that you may need to restore from a backup. Also going forward its always recommended to have at least two domain controllers for high availability and disaster mitigation (which could have helped here)
