Look at your resolv.conf and make sure that it actually directs queries 
to your newly installed BIND.

Check the log for mentions of rejected queries, even though those 
shouldn't result in a timeout. The default configuration allows 
recursive queries from localhost and your local network.

If all else fails, trace the query packets with tcpdump and find out 
where they end up.
