Right click the folder, select "Share", assign it a share name. Set the "Share" permissions to "Full Control" for "Everyone", then set the "Security" permissions as desired. I usually give "Full Control" to "Domain Admins", "Change" rights to whatever users/groups need to edit stuff in the folder, and "Read only" rights to people who need to see the files but not change them. Map the clients to this share, and you're good to go.
Yeah...most companies aren't as granular with permissions as I am, but the types of companies I have worked for are REALLY picky on security, and rightly so.
BTW: I would avoid using such a low drive letter as F: for mapped drives. If you ever get a PC that has a card reader, it will have local drives going to about H: or so. J: is the lowest letter I'll use...exception: I use B: on my admin accounts to map to my install share, where all the good stuff resides...my users don't get this drive.
