Perhaps I should have said that Samba has to be authoritative for the 
dns domain, so you really do not need anything else controlling anything 
to do with dns.

I tested joining a Ubuntu DC to a domain and I had to do this:

apt install ifupdown
apt purge nplan

Edit /etc/network/interfaces

# The loopback network interface
auto lo
iface lo inet loopback

auto enp0s3
iface enp0s3 inet static
         address 192.168.0.243 <-- replace this with your DCS IP
         netmask 255.255.255.0
         gateway 192.168.0.1 <-- replace this with your gateways IP

Replace 'enp0s3' with your interface name.

service systemd-resolved stop
systemctl disable systemd-resolved.service

rm -f /etc/resolv.conf

create new /etc/resolv.conf

search domain.com
nameserver 192.168.0.243 <-- replace this with your DCS IP

edit /etc/hosts

127.0.0.1       localhost
::1             localhost6
192.168.0.243  ubutestdc.domain.com ubutestdc <-- replace this with your 
DCS data

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

reboot

The 'nameserver' should be the DCs IP, see above

I actually wanted to see the contents of the files, especially 
'named.conf.options' & 'named.conf.local'
