In order for your CYBRA account manager to create a valid license file for your system, we must first know your hardware Unique Server ID.  This ID is otherwise known as a 'MAC address'.  MMPI uses various methods for obtaining the MAC address depending on the operating system of the server.  If a server has multiple network interfaces, it will then have multiple MAC addresses, so it is very important to give your account manager the MAC address listed on this screen when requesting a license.
