We have a couple of Windows 8 users connecting with PPTP VPN. They use offline folders for their home folders on the server and previously had some common resources synced as well (we've removed these by now. When they connect with PPTP VPN they can't access the common drive until they inactivate offline folders. Folders are crossed out with a red x and they can't go online. They can ping the server name but that's about it. Server is a SBS 2011. Any suggestions on how to solve this?
