All of my users log into a desktop session to run their apps. I put a batch file in startup that maps them to their network drives. When I want to add a drive I edit their batch file in the startup folder of their user profile folder. This was working until I tried to change an existing mapped drive. Even if I change it in the batch file and save the batch file, when I run it, it will still map them to the old shared resource. The only way is to ADD a drive letter. The only way around this was to destroy the profile and start another one. I cannot find a switch or file that is keeping a record of these drives. Any ideas?
