Hi Yogeshwaran R,

Thank you for posting in the Microsoft Community Forums.

Check Kerberos authentication:

Ensure that time is synchronized across all domain controllers.

Reset the secure channel between domain controllers using the netdom resetpwd command.

Clear the Kerberos ticket cache by using the klist purge command.

Check the DNS configuration:

Ensure that the DNS servers are configured correctly and that all domain controllers can resolve each other's hostnames.

Check that DNS records such as _msdcs, _sites, and _tcp are complete and correct.

Check and repair the replication configuration:

Use the repadmin /showrepl command to check the replication status.

If replication problems are found, try to force synchronization using the repadmin /syncall command.

If the replication partnership has been corrupted, it may be necessary to re-establish the replication partnership.

Troubleshoot network issues:

Check the network connection to ensure that no firewall or routing settings are preventing communication between domain controllers.

Use tools such as ping, nslookup, and telnet to test network connectivity and port reachability.

Fix system or software problems:

Check system event logs for replication-related errors or warnings.

Ensure that all domain controllers have the latest security patches and updates installed.

If system file corruption is suspected, try using System Restore or reinstalling the operating system on the domain controller.

Other possible resolution steps:

If none of the above steps resolve the issue, try restarting the domain controller or the entire domain environment.

In some cases, using the dcdiag command can help diagnose more complex domain controller problems.

Best regards
