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.

Subject: prevent DHCP server giving out leases to non-domain machines?

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?
Kind Regards
Murad Talukdar
