how can i remove normal user access to mount and smbmount??

the reason being - i'm sharing stuff on my windoze machine, which i mount as read-only filesystem on my linux box. But, because i'm sharing it on a Windows 2000 machine, my only option is to share it will *full read/write access*, and simply mount it as a read-only fs.

the problem is that any standard user is able to mount or smbmount this windows share into their own directory as a normal filesystem, and make changes, or delete everything!

i seriously need to remove standard user access to the "mount" and "smbmount" commands!!!

help!!!!!!!!!!!
