A family of Microsoft relational database management systems designed for ease of use.
This happened to me the other day when I was connected to a backend data file on my flash drive while I had the database open on my computer. I removed the flash drive from the computer and up came that message about "Your network access was interrupted ....
Do you have a shared backend file on a network server? Is the connection dropping out when you see that message?
If you can't prevent the interruption to the connection to the backend data file, your users need to know why their database won't work.
If you provide some more information about when this error happens, we can help you with more appropriate information.
