Herman,
My first suggestion is upgrade bind right away, and make it your first
priority. I suggest upgrading to bind 8.2.3, because bind 9 is a lot more
picky with the db files and can cause certain domains not to work. If you
haven't heard there is an exploit in bind 8.2.2 that can get a hacker root
on your box. This is a very SERIOUS problem, I have already seen 10 servers
on our network hacked since this came about. You may want to look into
alternative software for DNS as well (djbdns is the only one that comes to
mind), because I think many people are getting tired of the problems with
bind.
