Hello all, I am the equipment manager for a DJ service. I recently talked my boss into letting me build windows based systems for our DJ's to use instead of a prebuilt DJ console that would cost more than twice what my design would. One of the biggest concerns we have is the ease of one of our DJ's to simply bring an external HDD with them and copy our music library while they are at a gig. Licensing and legal use of music is a top priority to us. All of my searches online have not yielded any useful information. I need to find a way to restrict a user from copying and moving files, but still give them access to play the music files. Is there a way to do this without buying an extra security program?
