The management server counts each license for clients on physical computers, whether the computer is online or offline. For virtual clients, the management server counts the licenses of online non-persistent clients only. Offline non-persistent clients do not count. Make your virtual clients non-persistent if you have more users than you have clients.
To mark a virtual client as a non-persistent client, you must create a registry key in the base image.
To manage the license count for non-persistent VDI clients
After you have installed the Symantec Endpoint Protection client and disabled Tamper Protection, open the registry editor on the base image.
