I asked the following before:
"Is there a way to schedule a maped network drive using task scheduler. For the purpose of a backup schedule, I only want to map a network drive two days out of the week. I hope that this is possible."

And I got the following response:
"Yes there is, type in your mapping command and save it as a batch file, eg. map.bat and pick this file in the task scheduler."

Now I have the question of what is the mapping command (for DOS?)or how do I do this? I need more help/details. Thank you for your time.

You will need to use the net use command to map a drive from inside a batch file. More info can be found on the net use command in the windows help files or by opening a command prompt window and typing net use /?

Thank You.
