In Windows 2000/2003 DHCP, you can add reservations. This only works if you know the MAC address of all good clients, and add any new machines that have been authorised to use the network. You could probably script a way to add clients to this list. Unfortunately my own scripting is sub-par so I can't help out much with it but it is one thing I shall be pushing for when/if these SOX audits ever calm down and I get a bit more time on my hands. -----Original Message----- From: rolando_ruiz () jetaviation com [mailto:rolando_ruiz () jetaviation com] Sent: Friday, 28 July 2006 2:24 AM To: security-basics () securityfocus com Subject: Deny client from obtaining IP address Hello all, Is there a way that in DHCP or so, one can deny a client computer from obtaining an IP address? We use Microsoft servers ADS environment and I'd like to allow only those we want to obtain an IP address. I don't want to make it too restricted where authorized users are unable to connect. I'm sure there are some 3rd party apps that can handle this and I welcome suggestions on those also. This is a solution for denying connectivity to outsiders.
