unexpected RCODE

[Mark Watts]

I keep getting the following type of messages in syslog on a bind 9.3.1 box 
(its an internal dns domain - not visible from outside the network):

Mar 22 16:34:24 ins0 named[2086]: unexpected RCODE (REFUSED) resolving 
'blog.mq.eris.qinetiq.com/AAAA/IN': 128.98.76.115#53

I get lots of these, all for machines on the mq.eriq.qinetiq.com domain, which 
should be being delegated to the IP address given.

The zone file for eris.qinetiq.com has the following in it:

mq.eris.qinetiq.com.                IN  NS      ns0.mq.eris.qinetiq.com.
ns0.mq.eris.qinetiq.com.            IN  A       128.98.76.115

What do these messages mean, and are they a result of a misconfiguration on my 
dns server, or theirs?
