There are two ways to "join a workgroup"
The most common way is on a shortcut command line (on the desktop or
something):
"C:\...\MSACCESS.EXE" /wrkgrp c:\...\system.mdw c:\...\YourProg.mdb
("..." means whatevers specific to you. Also, it might not be called
system.mdw etc)
(you MUST specify msaccess.exe, further shortening it wont work to pass
parameters)
Another way (to set the default workgroup for ALL mdb usage):
(later versions of Access)
Tools/Security/Workgroup Administrator
(earlier versions of Access)
might be Wrkgadm.exe
By using the first way (separate shortcut for your database), you wouldn't
affect other access usage, such as some people double-clicking on other mdb's
which would use the "default workgroup" (whatever it's set to).
If you have multiple versions of Access on the same PC, then I may have cut
you short
