Hi,
Thanks for posting in Q&A platform.
Based on provided information, my understanding is workstation 1 windows 10 client cannot access to resources in DC2 by \hostname of DC2 but can access by \IP of DC2. If my understanding is wrong, please correct me.
Please run command nslookup + hostname of DC2 to see if the name can be resolved by DNS server which was configured on Windows 10.
If not, could you please help post the result of ipconfig /all in Windows 10 client for further troubleshooting.
And regarding of error "The security database on the server does not have a record for this computer", I would suggest you could post a new thread in our forum for help since we may focus on one issue in one thread. Thanks for your understanding.
Best Regards,
Sunny
