It appears I've discovered some kind of glitch with the
lastest version of bind included with Redhat Linux 6.0
(8.2-6).

I've got two internal dns servers running bind.  One
primary, one secondary.

The job of these servers is to resolve local domains ONLY
and forward all unresolved requests to one of two domain
name servers on our firewall for resolution.  A proxy type
configuration.

ALL machines in question were running Redhat Linux 5.2 with
bind version 8.1.2-5.  All errata files were installed and
external names were resolved just fine.

I then upgraded both the internal dns name servers to Redhat
6.0 and updated all files with errata.  The upgrade went
smoothly on both machines.  I then noticed that although
internal local domains were still resolving properly,
all external domains would NOT resolve.

I checked to make sure my config files (/etc/named.conf) had
not been altered.  They had not.

I then took one of the name servers and uninstalled bind
(rpm -ev) and then reinstalled the one from Redhat 5.2.  I
then killed off the named daemon and restarted it.

This server then correctly resolved external domains
properly.

Here is my config file for the primary internal dns (NOTE:
my root.cache file is empty as all unresolved dns requests
get forwarded):

options {
        directory "/var/named";
        forward only;
        forwarders {

                207.250.113.67;
        };
        allow-transfer {
                207.250.113.0/26;
        };
        /*

// that's all folks


I would be more than happy to send you any additional
information should you request it.

Thanks.
