The message means that a machine at IP address
138.89.40.249
sent in a dynamic DNS request to your DNS server, and your DNS server
refused to honor the request because you have not authorized DDNS
from that IP address.
There is no proof that the machine at address
138.89.40.249
is a W2k machine. That IP address is registered in DNS as
ns1.bellatlantic.net
and I doubt that BellAtlantic (aka Verizon) would be running BIND
8.2.5-REL on a W2k server. I (and others) believe that Microsoft made
a design flaw when it made W2k workstations self-register (via DDNS) as
the default. It is a bad choice of defaults, it is NOT a bug.
As for why that nameserver is sending a DDNS packet to your DNS server,
you need to contact
dnsadmin at bellatlantic.net
That is the e-mail address in the SOA for the
40.89.138.in-addr.arpa
zone.
