Some times after administrator password changing or server that works long time with out reboot you might lose its secure channel to itself, eventID :
Event ID 4000:
The DNS server was unable to open Active Directory. This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.
Event ID 4007:
The DNS server was unable to open zone <zone> in the Active Directory from the application directory partition <partition name>. This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.
the fix is to re-establish the secure channel, from elevate command promp execute :
net stop kdc klist purge netdom resetpwd /server:127.0.0.1 /userd:domain.com\administrator /passwordd:* net start kdc
After that restart the active directory server
Good luck
Thanks! It worked perfectly on my 2019ess server
That worked for me! Many thanks
Hi, I’ve tried this, but I’m getting the following when I try to do the netdom command.
The machine account password for the local machine could not be reset.
An internal error occurred.
The command failed to complete successfully.
Looks like you having problem reaching the domain, try DCDIAG on the DC and make sure all is well with it
