Problems with Internal DNS

[Chris Joles]

Good Afternoon!

I am running Bind 9.2.1 on a Redhat 8 box.  This is running on an
internal network only.  Bind is name serving for 6 master zones.  All
of which point www.zonename.com to the same webserver and
mail.zonename.com to the same email server.  Everything seems to be
working with the exception of name resolution for the actual web
server.  The webserver is known as webserver.proteabhs.com , and when
a dns resolution is performed, it returns africaexotica.net with the
correct IP address.  Know, africaexotica.net is one of my zones.  It
is the first zone in alphabetical order that is on my dns box.  What I
want to have happen, is since the webserver is in the proteabhs.com
domain, I want it to resolve internally to webserver.proteabhs.com on
the proteabhs.com domain.  The only reason the other domains are
listed, is so if a user on our internal network needs to visit any of
the 6 domains that we are running websites for or if the send email to
any of the 6 domains that we are providing email hosting for.

What am I missing?
