You are probably going to find a lot more of these entries. By default,
Windows 2000 tries to send a DNS update to its known DNS server whenever it
starts up with a new IP from DHCP or finds its name to IP lookup entry not in
the local DNS zone.

 The big question is, does this mean Win2000's DNS server defaults to allowing
dynamic updates?

This is MS implementation of dynamic DNS. There is some more details on SANS
GIAC pages http://www.sans.org/giac.html

 `htm'. But which link do I want?
