OK, I have setup Arch in a VM and installed Samba and I got the same
error, no DNS update.

I checked /etc/hostname and it only has the short hostname in it, I
then checked /etc/hosts and it had three lines:

127.0.0.1 localhost
::1 localhost
127.0.1.1 archmem.samdom.example.com archmem

As a test I commented out the last line, left the domain and then
rejoined the domain, this time it worked without the DNS error.

I could get to like Arch, except for one thing, the install procedure
is archaic (is that what 'arch' is short for ?), the last time I used
such an install procedure was over 20 years ago :-D
