Blocking Mac Addresses from DHCP Server

Hi All,

I have a DHCP server running with roughly 400 addresses available for lease, however there are some entries that have no names and some are student laptops is there anyway of diasbling access to my DHCP server using its mac address? I like to keep tabs of what is on my network so need to disable this equipment from having access to my network. Any pointers would be welcomed.

Unfortunately DHCP has no such a device.. If you want to accomplish this you really have a couple of choices..

1) you can use MAC address filtering on a switch (lots of work!!!)
2) You can look at NAP (Network Access Protection).. I am not sure of the functionality in Server 2003 but Server 2008 would allow you to block access to the DHCP (but only for supported clients)
3)Cisco also produces software that will accomplish what you want.. but you need Cisco routers

I am not sure of any third party software that will accomplish this..
