Hello,
CALs are required when you have users or devices accessing services on a Microsoft server. This includes accessing resources such as files, printers, applications, or services hosted on the server. For example, if you have a file server and multiple users access files stored on that server, you would need CALs for those users or devices.
Not all server activities require CALs. For instance, if a server is used solely for processing tasks without direct user interaction, such as a database server or a web server hosting public-facing content, no CALs are needed because there is no direct user or device connection to the server.
When it comes to Remote CALs, it is specifically designed for scenarios where users remotely access the full desktop experience hosted on a server.
In your case, as a gaming server operator where users do not log in with individual accounts to access resources on your server, the typical requirement for CALs might not apply. Your scenario might fall under the exception where direct user or device access to server resources does not occur.
Licensing software with CALs and MLs can be complicated due to the technical nature of server products and networks.
The above is for reference purposes only. Before purchasing, you should consult your Microsoft representative or local reseller regarding your specific licensing needs.
