By default, dynamic DNS updates to zone on a BIND DNS server is not
allowed.  If you want to allow dynamic updates to a zone, then you
need to change the named.conf file to allos dynamic updates for that
zone.  Note the following caveats:

     1) Dynamic DNS updates from a W2k box to a BIND box are not
        secure.

     2) Once a zone on a BIND box is dynamic, you can no longer edit
        the zone file manually.  All updates must be via the nsupdate
        utility.

For more information on DDNS and BIND, search the list archives.  There
have been many postings on this subject in the past two years.
