All users are using a copy from a template of the same front-end.
2 users have begun to experience the following error:
DISK OR NETWORK ERROR
I've determined that when this error occurs, the program has 'lost' its link with the back-end. By navigating out of the program with the error back to the main menu, then back into the program that had generated the error, usually the error message will go away. I AM NOT leaving the MS Access database, merely navagting around in the database program.
All other users continue to operate without a problem. Most of the users are MS Vista Business, (including the two workstations that are failing).
One of the workstations is getting increasing numbers of error messages, to the point that it is fruitless to continue.
