This is nslookup telling you that out of the nameservers in resolv.conf,
it decided to ask 192.168.12.5 this time.

No, your nslookup client asks kdc01.

And you are basing this on what kind of observation? I'm pretty
confident that the forwarder code uses the IP address you set in
smb.conf when it decideds to forward. Pretty confident as in "that's the
way I wrote the code" :).

I'm not sure you're doing anything wrong, DNS is slightly more complex
that one initially thinks. :)
