    Jake,

    With Windows you can assign dhcp to a mac but it does not always work
    because if a request comes in and the client is not online even if you
    have assigned that dhcp address to a specific mac address it will still
    hand it out. My suggestion is to run a Unix DHCP server because it will
    hold those dhcp addresses to that mac and only let those macs have that
    address. I know that this is not comforting but it has been the only
    way that I have found to do this.

    Subject: Filtering DHCP Assignments by MAC Address

    We have just converted to DHCP and would like to limit the ability of
    people
    to plug in to the network without authorization. In Win2K is it
    possible to
    limit DHCP assignments by MAC address or some other mechanism to keep
    rogue
    machines out? My server admins have been researching this but can't
    find a
    method to achieve what we want. Thanks.

    Jake
