Appendix A : User Administration
Introduction
Logic MMC uses Microsoft Windows NT as an operating platform for the Encore software. This provides a stable
working environment with a range of user supportive features such as security and the logging of diagnostic
information.
This is a ‘secure operating system’ and allows individual users to be setup before using the system to prevent
unauthorised access to other user’s files, system-wide parameters and settings. This involves giving the user a
Username, a Password and membership of a Group.
These instructions assume a knowledge of graphical operating system concepts, such as using the mouse for
clicking on buttons and selection of fields for data entry. It also assumes a knowledge of basic computer
concepts (e.g. files and directories).
The Modem
A modem is provided so that technical staff at AMS Neve can perform remote diagnostic activities by accessing
logging data recorded by Encore and Microsoft Windows NT.
Please ensure that an external telephone line is provided for connection to the modem.
The instructions provided here are for systems using Windows NT version 3.5. The procedures described are
similar for Windows NT version 4. The Windows NT 4 User Manager can be found in Start -> Programs ->
Administrative Tools (Common).
Administration Terminology
This section explains some basic terminology used in secure operating systems. It is intended for users who have
no prior experience of such systems.
Users
Users are the actual operators who use the system. It is possible for a single user to log in with different
Usernames, and conversely it is possible to have a single Username which is used by several users (this is not
advised).
Logging In and Logging Out
‘Logging in’ is the procedure whereby access to the system is granted by entering a correct combination of
Username and Password. The term login is generally used to describe the action of logging in.
Logging out (or logoff) causes the system to terminate the current session of Microsoft Windows NT usage, and
the system will not allow any further activity to take place other than shutting down the system completely or
logging in again with a valid Username and Password.
Username and Password
The Username is a means of identifying a particular operator to the Microsoft Windows NT system. Each
Username has a Password associated with it and the correct Password for a particular Username must be
provided by the operator to gain access to the system.
Groups
A Group is a means of identifying what class of operator a user belongs to (e.g. Engineer, Technician, etc.).
Within Microsoft Windows NT, each Group has various Rights which allow or restrict the functions which may be
performed by members of that Group. A set of Default User Groups is supplied as part of the Logic MMC
installation.
