The chances are pretty good that the
.mdw file is the
workgroup file for that
.mdb database. (The
file does not need to have the same name as the
because several different
.mdb files can all share the same
workgroup security settings.)
To access an
.mdb file that has user-level (workgroup)
security enabled you need to open it using a shortcut (or command-line
invocation) of the form
"C:Program FilesMicrosoft OfficeOffice14MSACCESS.EXE"
"C:UsersPubliculsulsTest.mdb" /WRKGRP "C:UsersPubliculsSecurity.mdw"
