The internal Samba DNS server acts like the primairy DNS server for your
internal domain. Only DNS queries for hosts outsite your local domain will
be forwarded.
You have two options, update your internal Samba DNS server with all
information of your internal domain or configure your "Partial DNS server"
with the DNS records needed for your Samba DC. For more info this
changing the DNS backend and this

Not clear what is going wrong...
What is the content of /etc/resolv.conf on your Samba server? What is the
output of: samba_dnsupdate --verbose on your Samba server?
