define OK - for internal use NS records don't matter at all because the 
only thing which matters is that the machines listed in /etc/resolv.conf

if it comes to the internet - it makes no sense have nameservers which 
are not listed as NS records

Warn 	SOA MNAME entry 	WARNING: SOA MNAME (tncsrv06.tnetconsulting.net) 
is not listed as a primary nameserver at your parent nameserver!
