You are on a Windows 7 system, which supports one user logged in at a time. I would be interested in seeing how this behaves on a Windows Server 2008 R2 system, configured for multiple users to be logged on at the same time (the default for remote administration mode is one user at a time). I do believe this is an artifact of the Windows 7 architecture (one user at a time) because Windows Server 2008 R2 has different "security zones" (rings) in its kernel implementation for access by different components (services, drivers, and users) which affect the presentation to the user. Also, persistent mappings are user specific. So if usera has two persistent drive mappings and userb has three different persistent mappings, usera will see his two when he is logged on and userb will see his three when he is logged on. Do you have the same persistent mappings for dt-user and service-user? You have also stated that you see no mapped drives when you run the service, so it seems as though starting the service first (and never having anyone logged in or dt-user) is an exception. Therefore, by extension of what you said above, you only receive the mapped drives if 1) the service starts first and then the service account logs in interactively, or 2) the service starts after logging in with the service account. Did you try both of these? But once the service "sees" the mappings, it retains it until: the service restarts? Does it matter whether the service restarts with someone logged on (i.e., the service account) or no one logged in? I do not think that you have explored all of the conditions required for the service to maintain its mappings, and that may be fine for your application, but then again, it may not be. That is for you to decide. Jeffrey Harris This e-mail and any attachments are intended only for the use of the addressee(s) named herein and may contain proprietary information.
