They symptoms are usually associated with mixing (incorrectly)
both internal and external DNS servers on the client NIC->IP
properties.

Internal clients must use STRICTLY internal DNS servers.

If that is the case, the internal servers will not only supply
any internal name resolutions, they will short circuit any
external conflicting names.

Yes, you are just band-aiding the problem -- it is usually
simple to fix:

Remove all external DNS servers from the clients NICs

(Your Internal DNS should resolve external names or forward
to do that.)

The name conflict is another problem, unrelated to your actual
issue if I have guessed correctly. (It's a high probability guess.)
