I see, no AD. No prob.
Here's a little background on how mutliple entries work:
The way the DNS client side resolver service on a client machine works,
(whether it's a DNS server pointing to itself, a DC, a client machine, or
any Windows machine for that matter) is that if the first entry doesn't
respond or comes back as a Null, it goes to the second entry and tries
again. But it takes the first entry out of the "eligible resolvers list" and
never goes back to it unless you restart the machine, restart the DNS client
service or make a reg entry to alter that behavior. If there are 3 entries,
then it repeats to the third and removes both entry 1 and 2 out of the
eligible resolver list. So there is no "failover" per se, unless ALL the
entries have the SAME EXACT ZONE INFORMATION.
It's designed to be a fault tolerance solution and not a load balance
solution. So this would explain the behavior that you're experiencing. If
there is specific info on the internal DNS that you ALWAYS need, I would
suggest to install another DNS server internally, make sure all your zones
are on both machines (Primary/Secondary) and point only to both of them.
To achieve Internet access while only using your own DNS servers, use a
forwarder on BOTH machines, as outline how-to in
http://support.microsoft.com/?id=300202.
Hope that helps you in your solution.
