I have an ODBC connection created to an IBM server. This connection is used by Excel files to read data from this server. I want to restrict users from changing any of the ODBC settings either in the Excel file or in their control panel. As users can also modify/delete data from server by SQL command. Please guide me if there is any user rights setting available in Windows XP/7 by which I can restrict users from changing ODBC connection settings in the system.
