We have a laptop user who frequenty travels betweeen two company sites in WY and MN. These two locations are connected together via VPN and have a Windows 2008 server at each site running DFS to synchronize files between themselves over the VPN. When he is at the WY location, he uses a desktop computer running Windows XP that has the My Documents folder redirected to the DFS share on the local server there so that any changes made to the My Documents folder on the desktop are synchronized back to the MN location's server. The laptop, running Windows XP, has the My Documents folder saved locally on the laptop itself. The files that would be synchronizing would be very large, so the laptop would need to synchronize only with the server local to the location he is currently in. What is the best way to get the laptop's My Documents folder to synchronize based on which location it is in?
