SUMMARY
This article shows you how to share a secured Microsoft Jet database on a network. For a group of users to gain access to a secured database, the users must join the same workgroup information file. In Access 2.0, the workgroup information file has the extension .mda. In Access 95 and 97, the workgroup information file has the extension .mdw.
MORE INFORMATION
NOTE: This example assumes that the workgroup information file is named Secure.mdw.
- Share the database in a folder that has change permissions for the users (read, write, create).
- Share the workgroup information file, Secure.mdw, to a folder that also has change permissions for all the users. This folder may be the same as the database folder if the workgroup information file has a file name that is different from the database file(s).
- Create a shortcut that includes the /wrkgrp command-line option, as in the following example
"c:\Program Files\Microsoft Office\Office\Msaccess.exe" "\\srvr\fldr\MyDB.mdb" /wrkgrp "\\srvr\fldr2\Secure.mdw"
WARNING: To guard against the file becoming corrupted, share only a copy of your Secure.mdw file on the network. Back up a copy for safekeeping. You may want to do the same for the database file(s).
NOTE: This example assumes that the workgroup information file is named Secure.mda.
- Copy your database and your Secure.mda file to a network shared folder that has change permissions for the users (read, write, create).
- Copy the C:\Windows\System\Msacc20.ini file (or the WinNT\System32\Msacc20.ini file for Windows NT) to a new file name, for example, MyDB.ini.
- Open the new .ini file in any text editor, such as Notepad, and change the line that begins with SystemDB= to read as follows
SystemDB = \\srvr\fldr\Secure.mda
- Copy the new .ini file to the same server location as the database.
- Create a program item or shortcut that includes the /ini command-line option, as in the following example
"c:\Access\msaccess.exe" "\\srvr\fldr\MyDB.mdb" /ini "\\srvr\fldr\MyDB.ini"
Special Note for Windows versions: For Access 2.0 on Windows 95, Windows 98, or Windows NT 4.0, you can e-mail the shortcut. For Access 2.0 on Windows NT 3.51 or Windows 3.1x, have each user create the same program item in the user's Program Manager.
