Usually in MS systems any device requesting for IP address will get IP from DHCP server without any authentication. DHCP MAC address authentication can help prevent unauthorized devices to connect corporate network.
With DHCP Server Callout DLL installed Windows administrators can filter DHCP requests to DHCP server by Mac address. DHCP Server Callout DLL checks if this device MAC address is present in known list (text file) of MAC addresses configured by administrators If it is present, device will be allowed to obtain IP address or device requests will be ignored based on access list configured by administrator.
The Callout DLL (read: hook-in DLL) also works and should continue to work on Windows Server 2008 .
This DLL will help administrators to enforce additional security into network. After installation, both the DLL (MacFilterCallout.dll ) and the installation/configuration instructions (SetupDHCPMacFilter.rtf ) are available under %windir%system32.
