Can DHCP be made to force the use of a different IP for each lease?

I am not up on the various DHCP implementations and the tricks with them, does anyone know if there is a way to have DHCP give out a *different* IP each time, or at least a very good chance?

Thanks Arnold - I thought about a shorter lease time - but I would think the DHCP server would just keep giving the same IP out to the same client unless it was exceptionally low and the number of IP's was slightly too small.  What would you do in terms of lease time and IP number to increase the odds that a different IP is given out?

I realize it's a strange request - in the full context of the situation I am dealing with it is the desired option.  Thanks for all the help guys, I think it's clear that DHCP doesn't have any backdoor methods to accomplish this, outside of tinkering with pool size and lease time.
Have not looked at it directly, but if you are open to using non Windows Based DHCP server, you could look at whether a linux/unix based DHCP could be setup and use an external program that will act as a check on whether an IP should be issued to a system (based on MAC address).
note: all computers know their last ip address, and will ask for this ip address if available the dhcp server will give it to them
