DHCP MAC Filters – Part 01 – Enable DHCP MAC Filters

This Tutorial addresses:
Windows Server 2012 DHCP server also allows the administrators to specify the filters using which the administrators can filter out the specific MAC addresses to allow or deny them to receive the DHCP services from the DHCP server.

When a MAC address is added to the Allow filter list, only the added MAC address receives the DHCP settings from the DHCP server, and all other computers do not receive the settings whatsoever. On the other hand, when a MAC address is added to the Deny filter list, all the MAC addresses receive the DHCP settings from the DHCP server except the one that has been added
to the Deny filter list.

In order to configure the DHCP filter list as discussed above, you must log on to the DHCP server using the appropriate account credentials. This means that if you are about to configure the settings in the DHCP server that is present in an Active Directory domain environment and is a member of the domain, you must log on to the computer using the Enterprise Admin or Domain Admin account credentials. On the other hand, if you plan to configure the settings on a standalone Windows Server 2012 DHCP server, you must log on to the computer using the local administrator account.

In this two-part tutorial series of working with the DHCP MAC filters, in the first part you will learn how to enable the MAC filtering in the Windows Server 2012 DHCP server. In the second part, you will learn how to keep a particular client computer from receiving DHCP services from the DHCP server.
