I have set up roaming profiles and redirected folders in an sbs 2011 domain, using GPO.
I have configured desktop and documents to be redirected, and everything else as a roaming profile.
For laptop users I assumed that when they took their laptop home that the desktop would be available offline, and then would sync again when they connected to the windows VPN.
However, when at home the desktop is not available and thus produces an error - until they connect to the VPN AND refresh the desktop.
The server is sbs 2011
the clients are mostly windows 7, with some XP SP3.
The VPN is windows routing and remote access VPN
What is the correct setup for this scenario (most laptop users work in the office but occasionally take their laptops home at the weekend).
