Do you have 'dns.keytab' in /var/lib/samba/bind-dns/ ?

If you don't (I am willing to bet you don't), run 'samba_upgradedns' and 
downgrade to the internal dns server, then run it again, but add 
'--dns-backend=BIND9_DLZ'. This will upgrade you to the Bind9 dns server 
again, but this time with the 'dns.keytab' in the correct location.
