I do not know, I am not the one sat in front of the DC :-)
Does the jails /etc/resolv.conf point to its ipaddress (not 127.0.0.1)
?

There are quite a number of dns records on a DC that need to exist,
samba_dnsupdate checks that they exist and creates them if they don't,
it has nothing to do with client ipaddresses.

check /etc/resolv.conf, /etc/hosts /etc/hostname for a start.
