Access 2003 Workgroup File

My directory Application Data\Microsoft\Access has two workgroup files,
System.mdw and System1.mdw. Both have modified timestamps. How can I tell,
for a given Access 2003 database, which is the associated workgroup file?

Thanks,
Tony
 
Hello Anthony,

I understand that you'd like to know the associated workgroup file for a
given database. The default mdw file is actually user profile based. If a
Windows user joins a workgroup file, Access will open all database by using
the same workgroup file if you log on as that Windows user.

The default workgroup file is Application Data\Microsoft\Access\system.mdw
file. If you open the mdb file directly, the system.mdw is used by default.
However, if you once joined a different workgroup file, it will open that
workgroup file as default. You could check this after you open the
database, click Tools->Security->Workgroup administrator.

If you'd use a different workgroup file, you can create a desktop shortcut
that uses the appropriate workgroup file for that session.

The target of the shortcut would look like"path to msaccess.exe" "path to
mdb" /wrkgrp "path to secure mdw". For example:

msaccess c:\test\db1.mdb /wrkgrp c:\test\system.mdw

Technically speaking, a database can be associated with more than one workgroup file.

The mdw is associated with the session of Access, not a specific mdb file.

Access ships with a workgroup named system.mdw, so that one is likely the original one, however it could have been modified.

If your 2003 database was secured properly, i.e. with the intent that it is only useable with one secure mdw, then you should only be able to open it while using the correct mdw file.

You can create desktop shortcuts to test out each mdw file - one of them should give errors, the other one should prompt for username/password.

"path to msaccess.exe" "path to mdb" /wrkgrp "path to mdw"

Thank you. I am still working on it. May be after the holiday. I am still
doing some reading to understand [1] the best setup for a C/S setup where
the data mdb resides on a file server and the front end mdb is on a few user
desktops (about 2-5), and [2] trying to understand how a power user would
not be able to break the security by supplying a different mdw file. I am
reading the available online resources, but if you have any input, it would
be most welcome.

Thanks!
Tony

Because a properly secured file can only be opened with the correct MDW file.
 
All mdw files share some things in common - the Users Group and the Admin User. It is very important that neither of these entities have permissions to anything nor own anything.

The Admins Group however, is different.

That is why you create a new mdw file, and then take the necessary steps to create your own 'super' user and remove everything for the Users Group and the Admin User. It is important to follow the steps exactly, or you can easily find that the Admin User still owns the database (and therefore can get at anything, regardless of their permissions).
