Ok, so I am looking for some software that has the ability to monitor the actions done to file on a server/network. I can't install any software on the server, so is there a program that can be installed on the client side that can monitor the files on the server? I just need to know who accesses what files and if they make any changes or not. Is this even possible? Thanks for your help!
