    Microsoft Windows NT Server 4.0 + IIS 4.0 + Service pack 6.0


    Valid NT user can bypass the administrator security policy "user cannot change password" and can change his/her password through web based ".HTR" application.

This is possible with disabled accounts also.

    Enter valid user id and password (who can not change his/her password).Enter new password. It is by passing the security policy "user can not change password" and password got changed.

    The following files can also be used for the same
