I have designed an Access DB, that is used by 3 employees. It is stored in a folder on the NT server. Periodically after they have worked on it and closed out of the program, and try to open it again at a later time, it is gone. I have searched their PC and the whole server and it is nowhere to be found. This has caused us much time in having to restore from backup and reentering data. Does anyone have any idea as to what is causing this and how to prevent it.
