We have a couple of split databases here at work, and suddenly they have started allowing single user access only. It is not every time they are used but when it happens, there doesn't appear to be a locked file anywhere.
Access to both the front and back end is denied with a message saying the back end is already in use.
Can anyone shed light onto what has caused the problem - no changes have been made to permissions etc and the problem is intermittent.
Thanks in advance
