As the title says, some of my users have set up offline folder syncing on Windows 7 laptops because they are out of the office at customer sites pretty frequently and want to have files handy. From time to time they may need to connect back into the network over VPN and access other folders on the file server. The problem we see is that from time to time they will connect, and even though they can see the mapped drive to the file server, all they can access is the folder marked for offline syncing and all other folders or files on that drive are marked with gray Xs. To make this a bit more confusing, other drives that are mapped are fully accessible, only the drive that has any offline folder is not. This does not always happen, but it is frequent enough that it is causing users to complain.
All laptops are Win7 Pro 64bit, the office has a 20MB fiber internet circuit and GbE network, Barracuda X300 Firewall, 2k3 and 2K8 file servers
Even though we don't currently use it, IPv6 is enabled on the clients' VPN connections. Currently use PPTP.
I've looked around a bit and can't really put my finger on anything that seems to resolve the issue. Disabling slow link mode doesn't seem to do anything. Anything else I can try?
Thanks
