I have an application that has a setting to allow users to use a file on a share on the server. This worked fine for all workstations but did not work to the T/S. The T/S is a W 2012 R2 server. What I discovered was this. If I address the file as \\servername\c$\share\my file.dat all is fine. However, if I address the file as \\servername\share\my file.dat no users including the domain administrator has no rights to this file. So it appears that there is a security issue with the share. I checked both the security and permissions and everyone has full control. What else can I check? I can go to any other computer and everyone has full control. It is only from the T/S where I have this issue.
