Odd one. Some offline files have been defined on a Windows 8.1 Pro PC on a share to a Windows SBS 2008 Server. There is another share to the same server with no offline files defined.
The trouble is, the share with some offline files usually ONLY shows the offline files, not the combination of offline and online files from the server, when connected to it on the VPN. Conversely, the other share shows all files on that share, on the same server at the same time????
It's like the PC doesn't recognise it is connected to the server so only shows the offline files on the share where they are defined.
