Question : custom ADM which will restrict and hide all drives except F on Windows 2008 Server

We have a windows 2008 R2 server which has 3 clients who connect to through Terminal Services. We have 3 seperate drives for each customer
We are trying to build an ADM which will allow us to restrict all the drives except the F G or E drive for a each company (e.g restrict and hide all the drives except F drive for company A)

We have created an ADM which is suppose to restrict and hide and all we have to change it the drive letter that we want to allow access. When we test this it restricts all drives and none are visable.

Could some check this for us and replace with what is wrong please
