DHCP with pool for "allowed" MAC for few IPs

Hello, I was wondering if it's possible to setup the DHCP service on my W2k3
R2 servers to only hand out IPs to clients from a list of MAC addresses. For
example I have a pool of 100 IPs with 150 MACs in the "allowed" list because
not more than 100 of them will be connected at any one time. And when they
connect, they are given the first available IP.

We currently have our DHCP servers setup so that every client is assigned
its own IP, but we're running out of available IPs to use. I've done this
before in the linux world using dhcpd, but I can't figure out how to do it on
my windows servers.

Could someone point me in the right direction? Thanks!

Windows 2003 Directly won't support this feature , but you can achieve this
by implementing the call apis..
Bellow is the blog url which talks about call out api.
