Q: 	

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.
