It'd be incredibly useful to be able to list active/inactive mapped drives on workstations. We commonly get requests to fix broken network drives, sometimes they are ones that were manually mapped outside of a group policy. We are left trying to track down what the previous path or drive letter was to get the user back up and running.

This will likely need to be a script to enumerate all profiles on a system (in the registry) to get their path and drive letter. I'd then be able to metric and track changes on it for our service desk techs
