    It is known about big hole in NT 4.0 security system
    that allows for a user without any access permission to mount NT
    server root directory (disk C:) in r/w mode and to take a
    complete control over NT system ? I heard only some little

Under 4.0 (no service packs) it is possble to mount drive C: (and any other
drive) R/W if you have a user account.  Note that this is the default
installation and therefore it is not a bug but a missconfiguration:

smbclient '\\ntserver\c$' -U user

should give you the smb> prompt.

Installing SP2 removes these defaults.
