Sure as long as your users do not need to add, edit or delete data. < g > Just make your data folder read-only. Otherwise, you have to go to a SQL backend for your data in order to get the security you are wanting [e.g., SQL Server, Oracle, etc].

The only alternative I can think of is to grant full access to the data to a single application UserID that is password protected AND unknown to your users. Then, in your app, login to that server using that UserID and password. During your app shutdown, logout that UserID. I can do this easily with Novell servers, but I am not sure about NT servers.
