I am using Windows Server 2012 R2. There is a shared folder on the server with name PublicFolder. There is an application which runs on server as well as on standalone reporting clients. These standalone clients are running on Windows 7 which are connected to the server. Whatever changes a client makes are updated in a xml file in this PublicFolder on the server. But, the client details remain missing who made these changes. I want to know which client made these changes on the reporting client that gets updated in the server (basically the hostname of reporting client). On each client, multiple users can also log in. How to track the users too?
