The system failed to register host (A or AAAA) resource records (RRs)

Server 2012R2

I swapped DNS updates to Secure only (with Credentails configured)

I can delete DNS record, do ipconfig /registerdns on client

Then in event log I get error:

The system failed to register host (A or AAAA) resource records (RRs) for network adapter with settings:

but DNS record DOES get created!

Which makes no sense at all?
