You will gain little additional security by doing this. As long as you 
can't prevent user from calling normal win32 applications (such as as 
cmd.exe) and win32 APIs (like CreateFile ()) he will be able to accesss 
any drives on your system you're supposing to prevent him from.
Your only gain will be false sense of security.
The way to achieve real security is to set proper access rights for all 
files on all filesystems on your host and all other hosts this user can 
log into.
