All of these logfile entries look to be DDNS updates that were rejected by
your DNS server.

1) Are your zone definitions configured to allow DDNS update (allow-update)
requests from dhcp clients? 

2) Is your DHCP server configured to send DDNS updates (nsupdate) requests
to your named server?

3) If none of the above, then you probably have some W2K or XP systems
sending a DDNS update request that needs to be disabled if you don't plan on
implementing DDNS. See windows tcp/ip->dns settings.
