DNS error

it looks like the zone cannot access the rest of your network
start with verifying connectivity between all the servers
test ping by IP, then ping by names. make sure all the DCs are accessible via name

Hi,

This is the error I get when running netdiag /fix. Not sure what is the best way forward. Please advise. Thanks

Hi

I had to start the server in dsr mode and use the  esentutl cmd to repair active directory. Would this cause the above error for the DNS? Do I have to reset the machine account password using netdom command and then starting and stopping netlogon and DNS?

Please advise.

Thanks

Is the DNS service running on the server mentioned in the log?

Yes it is running.
