           TEST: Dynamic update (Dyn)
              Test record dcdiag-test-record added successfully in zone domainname.com
              Warning: Failed to delete the test record dcdiag-test-record in zone domainname.com
              [Error details: 9505 (Type: Win32 - Description: Unsecured DNS packet.)]

I get this error when running "dcdiag /v /c /d /e /s:coad001 >c:\dcdiag.txt" from a domain admin account as an admin. We have been having some DNS issues as of late, in particular, DNS records are just disappearing. What appears to be the issue and how do I fix it?

Solution

I found an answer. Under my domainname.com zone, I had a com, then domainname folder. It contained a record which would return xxx.domainname.com.domainname.com.

I deleted this record and created it under the domainname.com zone. The error went away and my connectivity to xxx didnt go away

Seems like you have a DNS record under domainname.com with the name domainname.com, you are better check the DNS records for the problem
