About Parallels Pro Control Panel License

The Parallels Pro Control Panel license is a 25-character alphanumeric key used to determine the number of sites you can create on the Parallels Pro Control Panel server and the period during which you can use Parallels Pro Control Panel.

Depending upon your license key, the Parallels Pro Control Panel control panel contacts the Parallels Pro Control Panel licensing server after a specific time interval. During this communication process, the Parallels Pro Control Panel server sends the following data to the licensing server for authenticating your Parallels Pro Control Panel license:

• The Parallels Pro Control Panel version installed on the server
• The number of sites existing on the Parallels Pro Control Panel server
• The Parallels Pro Control Panel server's operating system name and its version
• Fully Qualified Domain Name (FQDN) of the Parallels Pro Control Panel control panel
• IP address of the Parallels Pro Control Panel server
• MAC address of the Parallels Pro Control Panel server's network card

The Parallels Pro Control Panel installation also creates a Windows Scheduled Task named EnsimLicenseScheduler on the Parallels Pro Control Panel server. After a periodic time interval, this scheduled task checks whether the Parallels Pro Control Panel control panel has contacted the Parallels Pro Control Panel licensing server automatically or not. If not, then it forces the Parallels Pro Control Panel control panel to contact the licensing server.
