How To Prevent DHCP Lease To Non Authorized Clients

Hello,

I am wondering if it is possible to prevent DHCP leases from being assigned from Windows Server 2008 to only MAC addresses that have been entered in to the Reservations section of the server.

Thanks,
Ryan

Why should you like that. It gives you more work because you must know the mac address from all your clients. Give the clients then a fixed ip adrress, but you must register them because to evoid ip conficts.
DHCP is must easier.

The problem is I need to be able to dynamically update information ... thus the DHCP server. I want to be able to lock it down to the MAC address so if they aren't on the list, I want the client to fail to find the DHCP server.

Is this possible?

So basically I am limited to using 802.1x ... which I don't have the technology to use right now. Thanks for the suggestions. Restricting the DHCP like this won't work as I keey the ranges seperated.
