Yes I remember the MS application - Scheduler2000. It was just that an MS application and it stayed on the server that everyone was connected to. The application took in information from the web by means of putting that information on the server and then the application sucked in that information off the server. Scheduler2000 was able to handle concurrent users. I think if a record was open by one user another user could not open that record until it was released. (I only used Access) and (Web focus to create the current status of tools etc.)
