Scenario. I have a firewall rule set that allows use of a particular service for a limited range of IP addresses (192.16.24.16/28 say) . I set up my DHCP server to give out this range only to users that validate themselves (basically this range is for a logical subnet withing a physical segment). So rather than changing firewall rules each time a member of that secure user set changes, the DHCP server validates users by things like NT group or challenge response etc. This localizes the security control to the actual owners of secure service.

DHCP hands out addresses, but where does it do validation for *services*? This is news to me! David G
