Network drives

I need to set the network directories a person can access everytime a workstation logs into the windows NT network. I was thinking to run a program right after logging happens and mount the desirable drives/directories from the server to the workstation. I have no clue however on how to do this, any help? Or direction to where I can find more info?

Thanks in advance,
Ninushka

Assuming there are user-to-user differences -

Considering using the login script each user has to make drive connections -
Net Use - Commands
