Unless you have an account and a password to map that drive in the batch it will fail and I would not advise that because its in clear text.. I would recommend using a Provisioning task to create the map drive and run the executable or whatever else, if possible.
How does that work with a Provisioning task?
Create a template map drive under System config and then schedule as a task?
Yes add the Map Drive action under System Config and then right click and schedule task. Here is the link to the Help: https://help.landesk.com/Topic/Index/ENU/LDMS/9.5/Content/Windows/osd_prov_r_action_types.htm
