Login script for Mapping

I need help with mapping one of the drive on the server to the users that login to that server.

Example: I have a server A with two partions and C: and D: drives. I want to map few users to D$ drive through the login script.
How do I do that. I don’t want to give them the administrator password. They need complete access to the D drive as we have applications there that needs the D drive to be mapped. I can’t use a shared folders as the application won’t work.

Please help.

Thanks,
