Let's go through some general troubleshooting steps to address these errors:
Inspect the specific error messages: Review the details of each error event to understand the underlying issues. Each error event should provide information about the problem it encountered. Pay attention to any error codes or specific descriptions that can help identify the root cause.
Check the Active Directory health: Ensure the overall health of your Active Directory (AD) environment. You can use tools such as DCDiag and Repadmin to perform diagnostic tests and verify replication status. Look for any reported errors or warnings related to Active Directory domain services.
Verify network connectivity: Ensure there are no network connectivity issues between the affected domain controller and other domain controllers in the domain. Check network configurations, DNS settings, and firewall rules to ensure proper communication.
Check system resources: Ensure that the domain controller has sufficient system resources (CPU, memory, disk space) available. Monitor resource usage to identify any bottlenecks or performance issues that may be causing the slow response.
Update and patch the domain controller: Make sure your Server 2016 domain controller is up to date with the latest Windows updates and patches. Keeping the system updated helps address known issues and improves stability and performance.
Analyze Active Directory event logs: Examine other related event logs such as System, Application, and Directory Service logs for additional error events or warnings that may shed light on the issue.
Consider specific error troubleshooting: Each error event may have its own troubleshooting steps and resolutions. Research specific error codes or descriptions to find more targeted solutions for the individual errors you mentioned.
Seek Microsoft support: If the issue persists or you need more in-depth assistance, consider reaching out to Microsoft Support. They can provide specific guidance and help troubleshoot the issues based on the detailed information gathered from your environment.
Remember to perform thorough backups and use caution when implementing any changes or fixes to your domain controller.
