Using Books Online
------------------

1. From Control Panel, double-click on the System icon.

2. Click on the Environment tab.

3. Under "User Variables for [Username]," change the value of TMP to a
   non-existing directory name, or delete or rename the existing directory
   pointed to by the TMP variable.

4. Run Books Online. You should get the following message:

   "Run-time error '3043', disk or network error"

Using DAO
---------

1. Repeat steps 1 to 3 as above.

2. Start a new Visual Basic Standard EXE project.

3. Add one of the following references to your project:

    - Microsoft DAO 2.5/3.0 Compatibility Library
    - DAO 2.5/3.5 Compatibility Library
    - DAO 3.0 Object Library
    - DAO 3.5 Object Library

4. Add the follow code to the Load event procedure in Form1:

       Dim WS as WorkSpace
       Dim sPath as String
       sPath = DBEngine.IniPath          ' This is fine
       Set WS = DBEngine.Workspaces(0)   ' Error at this point...

5. Run the project. You should get the following message:

      "Run-time error '3043', disk or network error"

To correct this behavior, create a directory (such as Temp) for the TMP
