Those are logs of dynamic updates that your name server received and
denied.  They may have been sent by Windows 2000 or XP clients,
which attempt to register their name-to-address and address-to-name
mappings using dynamic update.  To get rid of it, you can either configure
the clients not to send the updates, or send the category of message this
message is in to the null channel.  Through BIND 9.2.1, the messages
are in the security category; in 9.3.0, they're in their own category,
called update-security.
