V4.5.0 on Ubuntu 16.04.1LTS for the DC's 

V4.3.11 on Ubuntu 16.04.1LTS on member 

Hi Bob, try looking in syslog, is there anything like this:

samba_dlz: disallowing update of signer=WIN7-PC\$\@SAMDOM.EXAMPLE.COM

Rowland 

No, none like that. I see other samba_dlz entries of a positive nature. 

Thoughts? (Could this have anything to do with my recent dns issue? Is
some record missing?)

If you are not getting any 'disallowing update' messages but are
getting 'allowing update' ones, then it looks like your windows clients
are not trying to update the reverse zone.

If you are not getting any 'disallowing update' messages but are
getting 'allowing update' ones, then it looks like your windows clients
are not trying to update the reverse zone.

Rowland 

I am going to the location in a little while and I will sign on to other
(W10) stations and then test nslookups. 

The only client currently running is a W7 that I left running last
night. Let me see what happens when W10 on signed on. 

I have been "tailing" the log files for a couple of hours. Scrolling
back never found any "disallow" messages. 

(BTW, sorry about my silly email client messing up my replies.)
