I want to setup this server as a file server only. For example sharing documents and data across 10 computers, this is going to be the main purpose of the server. I'm not going to authenticate any user from withing the server. Do i still need to buy licenses for this 10 users, even though i'm not authenticating any user from the server? I will have drive c: as a share and my documents on the server, so that the other users could access this drive and folder. Do i need licenses to do this?
