Why do I keep getting messages of the form Jun 21 12:00:00.000 client 10.0.0.1#1234: update denied in my log?

I keep getting log messages like the following. Why?

Jun 21 12:00:00.000 client 10.0.0.1#1234: update denied

A:    
Someone is trying to update your DNS data using the RFC2136 Dynamic Update
protocol. Windows 2000 machines have a habit of sending dynamic update
requests to DNS servers without being specifically configured to do so. If
the update requests are coming from a Windows 2000 machine, see
http://support.microsoft.com/support/kb/articles/q246/8/04.asp for
information about how to turn them off.
