<vbg> I shoulda done that Yup, so it's only resolving from cache
for those that did hit it I see.

dig's +trace option can do the same thing, though its reporting isn't
as nicely formatted as dnstracer's:

dig +trace www.atbfinancialonline.com

First you'll see dig resolving "." (the root domain), then getting the
master servers for "com.", then for "atbfinancialonline.com."

allow me to jump in here. I recently installed dnstracer (from rpmforge),
but I don't get the expected output on the machine where I want to use it.
All I get is output like this:

chacha:~ dnstracer www.atbfinancialonline.com
Tracing to www.atbfinancialonline.com[a] via 127.0.0.1, maximum of 3
retries
127.0.0.1 (127.0.0.1) Refers backwards

This is on the server that provides local dns caching and dns for some
local non-public domains and reverse dns for the LAN. It's configured to
use a forwarder.
I may have misconfigured something in bind?
