DHCP Based on MAC address

[nodeel]

heres a doozy.


We currently have a Linux machine that handles DHCP based ONLY on MAC address. So, a user who wants access to our network gives us their MAC address, we add it to the list, and restart DHCPd, and away he goes.


NOW, unfortunately, we're moving to an all MS Win2k Advanced Server (our director mandated this change, not me....grr)...


I've been unable to find a way to use Win2k Advanced Servers DHCP to base leases for IP addresses by MAC address. I know you can "reserve" ips based on Mac address, buts thats not what i want, as the users we have are very fluid....they disappear for months and I dont want them hogging up an IP address.


is there a way for Win2k's built in dhcp utility OR A THIRD PARTY UTILITY (provide linkage if you know of one) that can handle DHCP duties based on MAC address?

So, heres what i'd like:

We have a "pool" of IPs that are assigned via DHCP, but ONLY to users on a dedicated MAC address list. ALl other users are either forced to use static IPs or locked out of the network altogether.


Any help is appreciated.

Thanks!

You can run both servers, only with the Linux server coordinating the MAC addresses. You do not have to use 2k's DHCP or DNS if you don't want. The alternate is to use virtual MAC addresses, whereas mobile users use a static range of MAC id's you manually assign.

so it isn't an option to keep a linux machine as the dedicated DHCP server?

I would ask them why they want to swtich to a closed, very expensive replacement for a free, working one. Sorry I can't help much on the real problem, but it seems stupid to swtich.
