What is llssrv.exe?

Part of Microsoft® License Server by Microsoft

What is it?

A license server is required when Terminal Server is deployed for hosting applications and desktops. A license server stores all Terminal Server client license tokens that have been installed for a terminal server or group of terminal servers. It tracks the license tokens that have been issued by the Microsoft License Clearinghouse (the service that Microsoft maintains to activate license servers and to issue licenses to the license servers that request them).
Description of llssrv.exe from Microsoft
A terminal server must be able to connect to an activated license server before license tokens can be issued. To help you with your deployment planning and to give you time to install a license server and add license tokens, there is a 120-day grace period after the first client connects to a terminal server that is running Windows before you must have a license server activated. After this period, if the terminal server does not find an activated license server, clients are denied access.
(llssrv.exe is a system file that is installed with Windows)
