Primary Domain Controller dns server host records are missing
-
What do the logs show on the first DC?
FYI, there aren't Primary or Secondary DCs anymore, those went out with Windows NT.
-
You normally would have DNS in a cluster and not recover an individual node.
-
If you have a system state backup you can restore the primary DNS zone... Or any DNS zone that was at least replicated to that DNS server

Primary DNS server all host records are missing exclude SOA records & Name server.
Kindly provide help, how to recovery primary DNS server with all existing host records ?You will need to check which one is the FSMO role holder, then move them if needed to the functional DC. Recreate your DC and be on your way.

primary dns server have fsmo roles. secondary dns server have all dns server host records. But, primary dns server dont have existing host records... if it is possible to recovery all existing host records again in primary dns server ??

Event ID 4013
hi , primary domain controller event viewer shows below error event id:
“The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.”

Yes, in this setup, AD does the underlying sync of DNS.

Now look in the AD DS logs and see if there are errors there.

if possible to export dns server records from secondary dns server and import dns server records on primary dns server.

Not for AD, no, I don't believe so.

any possible solution to fix the issues ?

AD is the issue, AD handles the database replication. You need to look at AD and figure out why it is failing.

Right - look at the AD logs and find out if there are any errors for you to correct.
-
Have you restarted DNS Client and DNS Server services on the DC with the problem? That should take care of it
-
You need your primary DNS zone back. I'd start by trying to restore that Primary DNS zone from backup.

@tim_g
they dont have any backups
-
ya we restarted already but issue the same

Then it must not be important enough to have in production or waste time on fixing... is my rough assumption.
