you didn't provide any configuration so I'm just guessing using

You have configured kerberos to look for KDC using DNS and DNS
server is not running.

What about selinux?
Also giving us only grep of logs are useless. There should be very

The problem mentioned with --disable-isc-spnego is only with
Windows client updates to the dns.
Please give us the named.conf (at least the part you copied
from samba) and also the named output from /var/log/messages
during startup (no debug is needed usually).
