Since the entire filtration process works on the basis of the MAC address of the target computers, it is important that you must know the MAC addresses before you start filtering the computers to allow or deny from receiving the services.
In your case, if you want to prevent a particular DHCP client computer from receiving the DHCP services from the server, you can add the MAC address of the target computer to the Deny filter list.
When you do so, all the DHCP client computers would be able to receive the DHCP services from the server except the one whose MAC address has been specified in the Deny filter list of the Windows Server 2012 DHCP filters.
Here is how you can create DHCP filters in order to prevent a DHCP client computer from receiving the Windows Server 2012 DHCP server services:
- Log on to the Windows Server 2012 DHCP server with the appropriate account credentials.
- If not already started, initialize the Server Manager window from the bottom left corner of the screen.
- On the opened Server Manager window, from the left pane, click to select the DHCP category.
- From the right pane, under the SERVERS section, right-click the DHCP server from the displayed list.
- From the context menu that appears, click the DHCP Manager option.
- On the opened DHCP snap-in, from the left pane, expand the server name. (DC-01.MYDOMAIN.COM for this demonstration.).
- From the displayed list, expand the IPv4 > Filters container.
- From the expanded tree, click to select and then right-click the Deny filter.
- From the displayed context menu, click the New Filter option.
- On the New Filter box, type the MAC address and a brief description of the target computer that you do not want to receive the DHCP services from the DHCP server in the MAC address and Description fields respectively.
- Once done, click Add to add the target computer of the typed MAC address to the Deny filter list.
- Close the New Filter box, and then close the DHCP snap-in when done.
