I have an application (front end) written in access 2000 with a database (access 2000 as well) in the back end. The application (front end) works in the client's machines and the database is sitting in a share drive in the network. The system was running fine and it started locking up. When it happens it does not let any user add, edit or delete records from the database. There is no errors whatsoever, nothing, it just locked. After a few minutes (sometimes a few hours) it unlocks by itself. This application had a few users and now has probably 25 or so. Any ideas what is going on?
