likely you have some users running Windows 2000 systems, which will
attempt to register themselves via `nsupdate` to whatever nameserver
is listed as primary in the SOA. You can either convince your users to
disabled dynamic updates via a procedure which was previously posted
here, or put something like "localhost.babcockbrown.com" in your SOA
record, such that attempts to nsupdate will fail. Naturally this can
break things if you rely on the NOTIFY facility but it's an option
nonetheless.

I'll copy the procedure to you for disabling Win2K nsupdate privately.
