Not that I really want to defend Access, but this should not be a problem for it. I am currently using a network database that takes data from 4 different VI's(on different machines) and multiple Access users, all at the same time. There is an occasional blip that I haven't figured out yet, where the database claims to be locked by a user, but that is rare.
Are you using a file DSN? You can set up the database for multiple users. I believe that the instructions are in the book that came with the Database Connnectivity Toolset. If you can't find them, let me know and I will see how I did it.
