That makes no sense. If you're sending a query packet directly to an 
authoritative nameserver for a zone, then recursion no/yes shouldn't 
make any difference to the result, since no recursion is necessary to 
resolve the name. Something else has got to be going on. Either the 
packet isn't going where you think it's going, the nameserver is _not_ 
actually authoritative after all, or maybe it *is* authoritative, just 
not in the "view" your query happens to be selecting (if you use "view"s 
at all, that is).

Post your config. If this is a publically-accessible domain, post the 
real domain name so we can take a look at it. Sometimes a few 
well-placed queries over the Internet can save hours or days of email 
back-and-forth on this list...
