Repeating the guidance from an earlier response to a similar query -

Hope you are specifying the file path correctly in the registry. And also strictly take care of all the following guidelines. It should work..

• First line in the file should specify the action. Action can be either ALLOW or DENY

o When action is specified as ALLOW, all requests from MAC address present in this list will be served by dhcp servers. All requests originating from MAC address not present in this list will be ignored.

o When action is specified as DENY, all request from MAC address present in the list will be ignored by dhcp servers. All requests from MAC addresses not present in this list will be severed by dhcp server.

o Only one action out of ALLOW or DENY can be specified in MAC Address List File

• MAC address should be specified in format XXXXXXXXXXXX (where X can be hex digit 0 - F).There should not any delimiter such as -, : in MAC address. Each MAC address should be specified in separate line.

We would recommend to use the MAC address filter feature which is inbox since Windows Server 2008 R2.

David, Windows Server 2008R2 supports MAC address based filtering inbox. We encourage you to use this inbox functionality. With the introduction of DHCP policies in Windows Server 2012, you can configue MAC address based filtering for each scope separately.

How can I filter MAC by DHCP Scope? The Dll filter MAC for all DHCP Scope.

Hey Tim,

There is no such hardcoding for the no. of MAC's in MAClist.txt

Thanks,

Is there a hard limit on the number of MAC's that can be in one MACList.txt file? I want to maintain one database for all of our locations, with a total of around 8000 devices. I would then just script the updating of the remote locations list from the master list.
