Database security 1

1 create a new workgroupfile (use WRKGADM.EXE). DO NOT NAME IT SYSTEM.MDW. If you use only one MDW then continue, else start WRKGADM.EXE again and switch back to the default system.mdw.
2 open access using this new workgroupfile (use a shortcut if needed see example)
3 open the database (file menu >> open) that you want to secure.
4 create a new user and add him to the admins group (this wil be the new administrator)
5 check that the admins group has rights to all objects in your DB!
6 change the default admins password from blank to something you will remeber.
7 remove all permisions from the users group in the database
8 close the database
9 reopen the database the database you are securing (use shortcut if needed!) and log in as  the new administrator
10 run the security wizzard on the new DB (saves time)
11 remove the (standard) Admin user from the admins group
12 create the users and groups your application needs
13 join your users to their rspective groups
14 assign the appropriate permissions to the groups
15 add or remove group permissions as needed.

You need a shortcut if you use several mdw's. If you're sure you will use only one mdw, than access wil always use the same mdw (as is set to default with WRKGADM.EXE) and you do not need a shortcut.
A shortcut example is: c:\program files\..\path to access.exe "path&filename of the database" /WRKGRP "pathname and filename of the newly created MDW file"
