By NOT giving any access to the drive where the database is located on
the server to ANY user.

Remember: The clients don't need to have access to the file, the access
ist handled by the Database-Server itself which is running on the
server(machine) and is called by the clients (gds32.dll / fbclient.dll).

This is the reason you always should install the Database-Server with
Admin rights.
