I am getting the following error after restoring an original image of DC after a day of running a backup image of the DC.
I have checked the regkey HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NTDS\Parameters where :
"Dsa Not Writable"=dword:00000004
therefore I did the following on the DC:
Repadmin /options –disable_inbound_repl
Repadmin /options –disable_outbound_repl
afterward, I restarted the AD services but netlogon service failed to start, therefore restarted the DC and netlogon is back but I still get Event ID 2092. What should I do to fix this. Also, users' network drive is also not connecting when using the DC name but works with IP instead.
Also netdom query FSMO gives the following:
C:\Windows\system32>netdom query FSMO
Schema master CAPRICORNFF.fairfield.ac
Domain naming master CAPRICORNFF.fairfield.ac
PDC CAPRICORNFF.fairfield.ac
RID pool manager CAPRICORNFF.fairfield.ac
Infrastructure master CAPRICORNFF.fairfield.ac
The command completed successfully.
This is the output of DCDIAG:

Event String:
The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server capricornff$. The target name used was DNS/capricornff.fairfield.ac. This indicates that the target server failed to decrypt the ticket provided
by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Please ensure that the target SPN is registered on, and only registered on, the account used by the server.
This error can also happen when the target service is using a different password for the target service account than what the Kerberos Key Distribution Center (KDC) has for the target service account. Please ensure that the service on the server and the KDC
are both updated to use the current password. If the server name is not fully qualified, and the target domain (FAIRFIELD.AC) is different from the client domain (FAIRFIELD.AC), check if there are identically named server accounts in these two domains, or
use the fully-qualified name to identify the server.

Time Provider NtpClient: This machine is configured to use the domain hierarchy to determine its time source, but it is the AD PDC emulator for the domain at the root of the forest, so there is no machine above it in
the domain hierarchy to use as a time source. It is recommended that you either configure a reliable time service in the root domain, or manually configure the AD PDC to synchronize with an external time source. Otherwise, this machine will function as the
authoritative time source in the domain hierarchy. If an external time source is not configured or used for this computer, you may choose to disable the NtpClient.
