I have an Access front-end database connected to various back-ends (Access, mySQL, dBase) which runs as a separate instance on each users computer. All users have Access 2007, and there are a total of 5 users for this system. Each user runs the database from their local hard-drive.
On one computer I am unable to open any of the linked tables and receive error message 'Unexpected error from external database driver (8458)'. Also, I notice that the Linked Table Manager is disabled (grayed out) when right-clicking on the table link definitions.
Oddly, if I create a blank Access database on this computer, I can create and open linked tables with no problem.
