Disjointed Name Space

[Tiffany]

My one and only DC had a NIC failure a couple of weeks ago and I've
been getting DNS errors ever since. Specifically, event 414 - "The
DNS server machine currently has no DNS domain name. Its DNS name is
a single label hostname with no domain (example: "host" rather than
"host.microsoft.com")."

I've entered the correct domain name under the registry key
....\Tcpip\parameters\nvdomain and and domain and rebooted. Still no
dice. If I look at the system properties, tcp/ip properties and
ipconfig /all, everything appears fine. It's only when I run netdiag
that you can see the problem. The computer name and DNS name are the
same, no "mydomain.com" in the DNS name. The host name has
".mydomain.com" - nothing for the place of the actual host - just the
domain.

Is there a fix for this? I really don't want to reinstall the domain.

Thank you,
Tiffany

I usually recommend using the script in this KB to fix a disjointed
namespace.
257623 Domain Controller's Domain Name System Suffix Does Not Match Domain
Name

If you can post these three items I'll take a look to see if there are any
other problems.

1. ipconfig /all
2. AD domain name from AD Users & Computers
3. List of Forward lookup zones in DNS and the status of the "Allow dynamic
updates" setting on the zones
