I have set up four Windows 7 computers with Access 2003 with the intent to be able to add data to a form in Access from each computer using linked tables to the database on one machine. Each machine sees the folder, can open and write to the form but not at the same time. Once one machine opens Access the others are blocked with a message that another user is using the database. This did not occur with XP.
