When using our terminal server - Server 2008 R2 x64 - users are unable to view files with Windows Photo Viewer.
Files can be accessed from anywhere (on the terminal server or the file server), either by double-clicking, right-click and Previewing or right-click and Open With. The error is as follows:
Windows cannot access <FILENAME>
You do not have permission to access <FILENAME>. Contact your network administrator to request access.
I am fairly confident that the problem is not a permissions issue with the files themselves, as they can be opened in any other application (e.g. paint) with no problems. I have replaced the permissions anyway, but this has not had any effect.
I am also fairly confident that the problem is not GP related, as it occurs for all users (domain admins included) and for a test user that I have created and to which no GPs are applied.
Users also have read and execute permissions on shimgvw.dll.
