	Note that nslookup refuses to use a configured server if it can't 
do a reverse lookup on the IP address.  Configure reverse DNS 
correctly for this IP address on your internal network, and nslookup 
should give you the same behaviour as you see with the application.

	Or, try using "dig" instead of nslookup.


	With regards to fixing the problem, you will need to take the 
information in the "real" zone that is external to your network and 
replicate that internally to your nameserver.  So, you will need to 
find out what the real Internet nameservers use for 
"pcaproxy.jazzkitchen.com" and put that into your internal copy of 
the zone.  Every time there is a change to the "real" jazzkitchen.com 
zone on the Internet, you will need to make the appropriate changes 
to your internal version of that zone.
