DNS Delegation Error
Hi Guys,
I'm getting the following error when running diagnostics on my DNS server:
We have three 2012 DCs and one 2008 DC.
Everything seems to be running fine with dns. The _msdcs is not greyed out. I've checked for old DC records and deleted them. Has anyone dealt with this issue before and have any troubleshooting steps I can follow?
Thanks!

Your comment put me on the right track. There was a "org -- mydomain -- lan" within "lan.mydomain.org". An application we use created a service record there. I deleted the string and re-ran that diag command and all was good. Thanks for your help.

The error deals with your DNS not including a zone 127.0.0 with one revord 1 IN PTR localhost.
Not clear which rests you are running dcdiag /testDNS
Ipconfig /all | find /I "name"
