Is it possible to disable the ability to Map a Network Folder

I administer a W2K3 domain for a medium company, and in the process of tidying up the domain, I have implemented logon scripts that handle the mapping of all required network drives for each user/client workstation. I would now like to disallow the privelege that allows users to map their own Network Drives, so that they don’t Map to the wrong data set. Is this possible?
