Why don't you simply deny the DHCP packets from that MAC address in the firewall.
But what happens when they catch on and assign themselves an IP address manually? wouldn't it be better so simply put an access list that denies on the gateway router or on the LAN switch?

Thanks Ernest,
Correct me if my interpretation of the conf below is wrong, but I think it
declares hosts 1, 2 ...(to whichever number I may feel like) along with their
MAC addresses after which it allows them to pick RANDOM ip addresses from a
pool.
This will not work in my case because it is hosts with known MAC addresses
that have their ip addresses fixed and any other to pick a random ip address
from a pool.
My problem now is that I want to be ban some MAC addresses from picking an IP
address completely!
