I hope you did install a more recent version of Samba4 then the one mention
in your howto.....

The Samba4 DNS server needs no further configuration, only needs a "dns
fowarder" in smb.conf, in your case it will be your NAT device.
Next your Windows clients should use the Samba4 box for DNS, if not Windows
clients cannot join your AD.

With the Windows DNS tools from the RSAT package on a Windows workstation,
you can query your Samba4 internal DNS server. See
the details on
