Safe Win9x?

[mojahed at citechco.net]

I want to install a linux samba server to serve 30 win9x machines. I
want to prevent users from writing on the local drives, they should
have write access only to their home dirs on the samba box. These
users have a nasty habit of deleting crucial system files.

Is it at all possible with win9x and samba? Of course NT workstations
could resolve the problem, but that's not an option with these
machines.

Many thanks in advance.
