You wouldn't happen to be using Windows 2003 AD for DNS behind a Cisco Pix 
firewall would you?

If so, there is an EDNS extension that M$ enabled in 2003 which allows two DNS 
servers to negotiate oversized UDP DNS responses.  The pix will drop those 
packets by default.

If this is the problem, there are at least two solutions.  Turn off EDNS 
negotiation on your directories, or update the Pix software and turn on the 
oversized DNS response fixup.  Google will get you the details.
