Well thanks for all the help, it is helping.  This could be the case
(and here we go showing my lack of dns & Linux knowledge).  But the
addresses of my internal network nodes are not defined in any dns
record, I did not think they needed to be defined because they are
internal, they are just ips assigned by the dhcp server.  What has to be
done to resolve this?  Do I need to define the whole ip range in dns for
my internal network, and what affect will this have on my dns records,
since my dns server is a the primary dns server for my domain, will it
try to supply these ips, even though they are not legal, to the outside
world?  Is there something else I should do, I was reading up on
/etc/host.conf file, is that something that affects this also.  Sorry
for all the basic questions, I'm trying to learn, but when they fire
your assistant and you have to worry about so much by yourself, certain
things get ignored (lame excuse I know).
Thanks a lot for all the help,
---Brian
