I have a bind server running that cannot resolve www.atbfinancialonline.com. I turned on "debug 10" in the named.conf and start up dig on it, but dig just times out, what else can I do to see why exactly it won't resolve this?
Thanks! jlc

Check what name severs are hosting the domain and try resolving directly from them.
atbfinancialonline.com name server dns1.cidc.telus.com. atbfinancialonline.com name server dns2.cidc.telus.com.
telus, sounds Australian ..seems like dns1.cidc.telus.com is not responding.
One of my Debian servers has a tool called 'dnstracer', I'd be surprised if it was available as part of the stock CentOS but maybe available in a 3rd party repo or some similar tool:
[aphro@portal:~]$ 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) |___ L.GTLD-SERVERS.NET [com] (192.41.162.30) | |___ dns2.cidc.telus.com [atbfinancialonline.com] (66.203.199.203) Got authoritative answer | ___ dns1.cidc.telus.com [atbfinancialonline.com] (216.123.224.131) * * * |___ K.GTLD-SERVERS.NET [com] (192.52.178.30) | |___ dns2.cidc.telus.com [atbfinancialonline.com] (66.203.199.203) (cached) | ___ dns1.cidc.telus.com [atbfinancialonline.com] (216.123.224.131) * * * |___ J.GTLD-SERVERS.NET [com] (192.48.79.30) | |___ dns2.cidc.telus.com [atbfinancialonline.com] (66.203.199.203) (cached) | ___ dns1.cidc.telus.com [atbfinancialonline.com] (216.123.224.131) * * * |___ I.GTLD-SERVERS.NET [com] (192.43.172.30) * | |___ dns2.cidc.telus.com [atbfinancialonline.com] (66.203.199.203) (cached) | ___ dns1.cidc.telus.com [atbfinancialonline.com] (216.123.224.131) * *

atbfinancialonline.com name server dns1.cidc.telus.com. atbfinancialonline.com name server dns2.cidc.telus.com.
<vbg> I shoulda done that:) Yup, so it's only resolving from cache for those that did hit it I see.

Calgary Alberta Canada! Wrong side of the planet:)

Nice tool, thanks Nate! jlc

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?
