Granting permissions to a folder but not the Drive

[WhereBob]

We are running Windows Server 2003 and have XP pro and Windows 7 pro on the client computers. I'd like to be able to grant permissions to users to this one folder (call it folder1) on a mapped F:\ drive but not to the mapped drive itself or any other folders and then map the folder on each clients computer. Can someone remind me how to do this, guess I have been out of school too long.

Thanks in advance
