- PC-Lock V1.3-2
- ==============
-
- Overview
- ---------
-
- PC-Lock allows the user of a PC to 'Lock' a DOS session, thereby inhibiting
- unauthorised usage of the machine during short absences such as lunchbreak.
-
- The PC-Lock program prompts the user for a password (and re-prompts for
- verification), and then prevents any further use of the machine until
- the correct password is re-entered.
-
- Once PC-Lock has activated (by entering a valid password and verification)
- there are only 2 ways to de-activate it:
-
- 1: Enter the correct password
- 2: Re-boot the machine (By power-off/on)
-
- Re-booting the machine is a rather ham-fisted way of gaining access to the
- machine, and will be obvious to the legitimate user, who will then investigate
- who has been using the machine in his absence.
