We are running Windows Server 2003 Standard Edition. Mobile users who have already cached domain credentials on their notebooks use a VPN to get to the network. This works. They can replicate their email (Lotus Notes) without a problem. However, when they try to access a previously mapped drive to a network file server share the Microsoft error dialog says they don't have permissions to the share because they are already logged on with that username. That makes no sense. However, if I disconnect the mapped drive and make it again while connected through the VPN, it works fine. One of my admins tried this same thing with his priviledged account. His experience was that he could get to the share, but could not see all the folders and the loose files in the root of the share.
