Hello,
Thank you for posting in Microsoft Q&A.
Based on the description, I understand your question is related to domain controller error.
Check that the DNS settings on your computers are correctly configured to point to the domain controller. Use the nslookup tool to verify that DNS entries are correctly registered.
Check that your computers are properly connected to the network. Use the ping utility to verify connectivity to the domain controller by its IP address and hostname.
Look at the system logs on both the client and the server for any errors related to network connectivity or domain controller communication. The event source for these logs is typically NETLOGON on the client and NTDS KCC on the server.
If your computers obtain network configuration from a DHCP server, try renewing the IP settings with the commands:
ipconfig /release
ipconfig /renew
Have a nice day.
Best Regards,
Molly
