What are you really trying to do here? Refusing a DHCP assigned address doesn't stop them from getting onto your network with a static IP. Should you be looking at 802.1x?

There are DHCP products that require authentication prior to giving out a DHCP address and these can be linked to AD. This can be setup to require a user to authenticate before the first IP address is handed out. During the renewals you might be able to use the Machine authentication to renew an IP address.

Hi, Is there a way to stop a W2003 DHCP server from giving out leases for IP's if a machine does not belong to the domain? Or is this a fruitless question that someone simply needs to point out something very simple to me. A machine can't join the domain if it doesn't have an IP first(chicken and egg type thing) I can see that but obviously I'm missing something here-perhaps it's a question of layers-the domain is working at a 'higher' layer?
