I have the following problem (on my boss' laptop) with offline files on Windows 8.1: everything works as expected in our LAN. If the device is attached to the network, all files can be accessed, if it is offline, only the ones marked as available offline can be accessed. However, when establishing a VPN connection from outside (we are using Cisco AnyConnect), the files remain offline (not connected, no slow connection). Furthermore, the button for explicitly switching between online and offline is greyed out.
Some background info: we are using DFS with the following structure.
\\domain\dfsroot\home\username is the path to the users' homes, which are (optionally) available offline.
\\server\homes\ is the share that currently exports all users' folders, so\\server\homes\username is the physical location of the above-mentioned path.
Each user is added separately in the namespace, ie we add \\server\homes\username in the DFS namespace, not \\server\homes as a whole.
When the laptop is in the problematic state, the user is able to access all other users' homes via\\domain\dfsroot\home\otheruser. The only path that is not working is his own folder. It is offline when using the UNC path, the mapped drive letter and the redirected shell folders. The DFS tab in the directory properties nevertheless shows that the share is OK.
I have already tried several suggestions from the internet, which did not help so far. These are: allow all authenticated users traversing\\server\homes, disable slow link detection via GPO, and ensure that IPv6 is enabled.
How can I enabled access to the user's share via VPN?
Thanks in advance,
Christoph
