I have just setup a server 2012 essentials R2 box as a test bed for my small business. Its running Essentials R2 as a VM on a Essentials R2 host. I have set it up to be the DC and DHCP server and joined a client. My next task is to use it as a file server but I am not quite sure how to set it up. All the client interactions with the file server will be through client side software. I therefore do not want any access to the files apart from through the software. I have looked at the ntfs permissions and there is a permission called "List Folder/Read Data" however I am unsure this will do what I want. Is it possible to give access to the files but not allow access through the windows explorer / command line?
