Why don't you use static ip addresses? Allow those you know, deny the ones unknown. This is also easier for accountability. Or, get to know the MAC addresses from the ones that are allowed to connect, and use that as a whitelist in your DHCP config. This is not totally secure, since one can spoof a MAC address. But it's a start. regards, Maurice Smit, CISSP On Thu, July 27, 2006 18:24, rolando_ruiz () jetaviation com wrote:
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.
