BIND can accept Dynamic Updates from Win2K clients as long you don't try to implement security.
This is because Win2K's method of Secure Dynamic Update (based on GSS-TSIG) is not compatible
with the standards-defined TSIG method.

Or, are you asking whether BIND can be used on a Win2K client to update a Win2K nameserver? I
suppose you could use the Win2K version of the "nsupdate" utility that comes with BIND to do
this, and in that case you could implement security via shared-secret TSIG, but the hard part
would be integrating such a function into the Win2K DHCP subsystem (it's not enough to just put
something in the system startup, since it's possible for a dynamic IP to change even with a
DHCP release/renew).
