They are updated by the AD DC at set intervals. This computer is configured to use DNS servers with the following IP addresses:

Yay! It works! The above error gave me the clue. I set the domain member to a
static IP (for now) and set the DNS to 192.168.0.2 (my DC) instead of the
router/dhcp-server at 192.168.0.1. The latter is still the gateway.

I then tried just joining the domain via Windows normal "Rename this PC
(advanced)", which is what I tried to do below, and that worked. I then unjoined
the domain and ran the ForensiT Transwiz tool to both migrate the domain user to
the new DC and join the domain. That also worked!!

The current/old DC uses --dns-backend=BIND9_FLATFILE so the whole DHCP and DNS
resolution was a different game. With that config the Windows computer "just
knew" to connect to the DC as the DNS. More experimentation needed with this new
SAMBA_INTERNAL backend.

When I logged in as the domain user it had some trouble because it's looking for
things (e.g.  Desktop) in the 'Redirected Folders' and on the NAS (not
connected), but otherwise it does look like the profile migrated.

Next step is to configure Group Policies, including Redirected Folders.

So far so good. Thanks to all for your help thus far!!!

Thanks -- Mark
