Domain name changed to Default-First-Site-Name

In Active Directory Sites and Services, the hm.local entry, our local domain, that's just above the Servers entries, was changed to Default-First-Site-Name. Can I simply rename it back to hm.local and restart the DNS service?

It's causing problems adding new network printers and new computer setup, everything else works normally.

AD Sites and Services does not list your domain name, it lists your site names. AD installs with a single site called Default-First-Site-Name, so the behavior you are describing is normal.

If you open AD Domains and Trusts and/or AD Users & Computers, I all but guarantee that you will see the domain name that you expect.

I did. I did some more research, and netlogon.dns has three 600 entries for our hm.local domain. Two entries are at the bottom of the list. Could the extra 600 entries confuse workstations attaching to the computer?

I read about how to rebuild the netlogon.dns file, but I don't want to mess with it unless it's the appropriate thing to do.

Restarting the netlogon service will re-register the SRV records contained in the netlogon.dns file; restarting the DHCP Client service will re-register the A records.

The netlogon.dns file is created by AD, so if it is inserting incorrect records then you should determine the root cause of said rather than simply deleting the incorrect entries. Is your domain controller multi-homed? If so, this is not a recommended practice.

I figured it out. The DHCP server had an external DNS server listed as the first DNS server. So users had no general DNS problems, but the external DNS server had no reference to our local domain. Ergo local domain references didn't work. Changing the default DNS server to the IP address of the domain controller and rebooting the workstations fixed the problem.

Thanks for your help. I'll assign the points to you.
