         Well reload does that and any zone file changes.  restart both deals
with changes to named.conf, the zone files as well as clearing cache and

         It turns out to be a tougher problem than I have time for right now.

         That's why BIND 9 is much tougher on enforcing the RFC's. You
sometimes need to force people to fix their problems as they won't do it
otherwise. It's not just stupid people, it's people who are short on time and have
deadlines they have to meet. And it's getting worse and won't get better.
