Deny client from obtaining IP address

[<rolando_ruiz () jetaviation com>]

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. 

Thank you
