does ISA server 2004 offer anything better in the way of DHCP or do you have the same options as in 2000? I am looking to try to find a way to secure a wap off of a ISA server ... I am also trying to find some kind of "secure" dhcp server to only hand out IP's to MAC addresses or by authentication would be perfect ... like when you go to a hotel and "log in" to get a dhcp and use the internet ...
