DNS - DCDIAG - Records Registration fails from Client, but not from DC - Windows 2008 R2 Domain

Greetings.  I've perused Experts Ex. for this problem and found several suggested solutions, none of which work.  When running:  dcdiag to test DNS from my workstation, the Records Registration test fails, showing missing SRV, CNAME and A records for the DC the test is run on.  We have three DCs and using any of them results in the same error.  The DNS settings on each DC are correct, in accordance with Microsoft best practices (1. Other internal DNS, 2. Other internal DNS, 3.127.0.0.1).

I've run ipconfig /registerdns for each DC - no fix.

I've checked that IPv6 ::1 are not listed as the first DNS servers.

I've run NLTEST /DSREGDNS to reregister DNS records for DCs.

When running the same DCDIAG test directly from the DCs, all tests pass.

Is this something I should be concerned with or just ignore ?

Thanks much.

nslookup works fine ... internal an external resolution
Yes, can ping FQDN of all DCs and other machines on network
Have run ipconfig /flushdns too many times to count :-)
