I have a database that had no password protection on it. All of a sudden, every morning, there is a Microsoft password applied to it. Every time we try to open the database, it prompts us for a password (not a form with code, but the security password access has built in). I don't set this up and I have no idea what the password could be. How can this be happening?? I have to copy over it everyday with another version of the db.
