In windows 7 using the file Explorer you could use a button to work back online, when you have been working offline.
Example after making a VPN connection to your home base, you could switch to work back “online” for all offline files and folders.
In Windows 10, this feature seem to have disappeared ?
But not realy ….
Once you are offline, first connect back using a VPN connection to your server….
And in the File Explorer go to EASY ACCESS next click work OFFLINE ?
This is the confusing part… even if you are working offline you need to click work offline again, to go ONLINE ?
You can monitor the status bar of the file eplorer at the bottom it should change to ONLINE.
The funny part is that the label of the Button “Work Offline” will never change to Work ONLINE
If this does not work in your case you can try to add this Registry Key, reboot and try again….
Add : SilentForcedAutoReconnect : REG_DWORD = 1
It did work in my case
