I've got an Access 2003 DB which I have split in to front-end and back-end databases using the Database Splitter. The backend (with all the tables) is on the server, in a shared directory with full control. The front-end (with the forms, querys and reports) is located on the Desktop. Any one user can open the front end DB - but no one else can. The next user gets the error message "Could not use <database path and name >; File already in use". It looks like the backend DB is being opened exclusively, but since the front end was linked to the back end using the Linked Tables Manager, I don't think that should be happening. This is a new install of Access 2003 on new WinXP box at a client site, and this has never been a problem before - but there's a first time for everything, I guess. There's something that I need to tweak - but it isn't obvious what. Thanks.
