Re: Deny client from obtaining IP address

you can deny a specific computer from receiving an IP address with the DNS 
settings in windows 2000 and  2003 based on its MAC address.  You can also 
assign IP's to specific computers in those settings as well.  step by steps 
should be easy to find in any current MS DNS book.

Additionally you could deny connectivity to a certain client computer at the 
router/switch level.  i know you can do it with Foundry and Cisco products.  

Since you question is a little vague that's the best answer i can give you.
