When users join a Microsoft Access workgroup by using the Workgroup Administrator, the location of the workgroup information file is stored in the Windows Registry, which means that in many cases all Access databases on the user's machine will use user-level security based on that workgroup information file.
However, you may want to use user-level security on a specific database, and not use it on others. To do this, don't have users join a Microsoft Access workgroup by using the Workgroup Administrator. Instead, take the following steps:
"C:\Program Files\Microsoft Office\Office\MSACCESS.EXE \\SalesSystem\DBFiles\SalesS.mdb /wrkgrp \\SalesSystem\DBFiles\SalesS.mdw"
