Has anyone got a fix for this?

I run a Windows 2000 Server Domain at a College. We have
been using Microsoft's DHCP to allot the Ip addresses to
students with network configuration information being sent
as part of the DHCP.

After the Blaster problem last year, it was felt that we
wanted to have more control over the IPs, so we introduced
a system of registration of MAC address and allotment of Ip
(in effect giving the users a static IP, except that they
have to dial-up to get it)

I have found that even though I have restricted the
addresses to be used and registered addresses to a single
MAC Address, where Xp and Windows 2000 clients are
concerned, they bypass this setup and just take any
address not actively being used at the time, causing lots
of Ip conflicts when the registered owner tries to use the
IP.

Anyone know a way to stop this - I suspect that it is a
symptom of them being more modern\same OSes and the same
principles as govern election of Master browsers is going
on?
