In case you don't have a 'named' process running on that very machine 
there is no local DNS cache.  Applications (DNS clients) just query the 
DNS server every time, and if it is remote and out of your reach there 
is nothing you can do about it, short of using a different DNS server.

However, if there is a local 'named' process you can get rid of its 
cache contents only by restarting it (AFAIK).  As user 'root', try

   ndc restart

and check '/var/log/messages' for the new startup message.  That should 
do the trick.
