Hello everyone! One thing I wanted to post about today was mac address filtering using DHCP on Windows Server 2003. The Microsoft DHCP team has a utility just for this called the Mac Filter Callout. It is essentially a DLL file, a.txt file and some registry settings that allow you to administer the DHCP filtering on your server. I want to Configure 'MAC Address' filter on my network to secure the environment; that ensures network access will be provided based on the authorized MAC address only. As first step implemented the DHCP callout DLL on my DHCP server.It working fine and only supplying IP address to devices mentioned specified in MAC list table.
Recently I needed to setup MAC filtering on our DHCP server and being familiar with Windows Server 2008 R2 I thought it was a standard feature. However I couldn’t be more wrong. Beyond two souls mac download. It turned out none of the previous server versions had this feature. So after a little searching I found an addon from Microsoft Technet that does the trick. It is called DHCP Callout. It is an MSI for 32 and 64 bit operating systems. So the installation is easy but it took me a minute to figure out how to configure it.
So after the installation you can access the files in the C:Windowssystem32dhcp. In that directory a few files are installed.
It adds log files, a config file, and a setup document. It also adds a few registry entries in HKLMSystemCurrentControlSetServicesDHCPServerParameters. These entries are as follows.
This is all covered in the setup guide as well. To setup the MAC filter list is pretty simple as well. You simply take you MAC addresses without and colons, dashes, or spaces and add them to the MACList.txt file. However at the top of the file you have to tell the DHCP server to allow or deny the MAC addresses that you have entered. Below is an example of the MAC filter list.
MAC_ACTION = {ALLOW}or DENY

We used this to improve security and to keep machines that are not ours off our DHCP server. All in all this works well. We found this out when we couldn’t get some of our systems to pick up an IP address from our server. Turns out we forgot to add them to the list. Anyhow we no longer have problems with systems controlled by another group of admins using up our IP space. So if you find this may be something that you are looking for you can download it at the following address.
This is a feature I have been waiting for way too long. Up until today if you wanted to
have some control over who is entitled to receive an IP address from your DHCP you either had to configure reservations (for each of your systems) or had to use some lower level device to filter out unwanted systems.Finally that is over now.
The Microsoft DHCP team has posted a new DLL called “DHCP Server Callout DLL” on their blog.
This DLL can be used on Windows 2003 and Windows 2008 DHCP servers to limit the scope of systems entitled to receive an IP address from the server based on their MAC address.
To install it you need to download the installer and run it.
