[Samba] Setup a Samba AD DC as an additional DC

[Barry D. Adkins]

>:~$ host 131.192.176.40
>40.176.192.131.in-addr.arpa domain name pointer sambaDC.
>40.176.192.131.in-addr.arpa domain name pointer sambaDC.local.

>>> Barry Comment: the name server for the Win Domain is set in Ubuntu Netplan.  I don't know why it did not find "pointer sambaDC.domain.com."
>>> I did not create a HOSTS file or make any entries as it was not on your "how-to".  Tried to follow exactly as you mentioned.  I'm working on getting this corrected.

I fixed this, but it didn't change anything about getting it to join the domain.  Same errors.
