unapproved update

[Bordelon, Greg]

These are more than likely from Windows 2000 computers. Microsoft has turned
on "Update DNS" in the TCP/IP tab settings by default. ;^(

On my name server I get a ton of logs that read

I am wondering why these logs are showing up.  I am an ISP and we are 
incharge (have authority for these classes).   I have read that window 
2000 makes these kind of requests, and that you can block at the router 
for certain queries. Does any of these hold truth.  How can I fix the 
logging so that I don't see just these or stop an "unapproved update".

thank you for your help.  I am running bind 8..2.2p5 and solaris 7
