I want Microsoft Outlook to have access but restrict those to all browsers (IE, Firefox, Chrome, etc.) I managed to find the LAN settings for Internet Explorer and configure the IP address to 192.168.1.1 with Port 30. This, of course, is a dummy address and restricts users from accessing the internet. As well, I changed the security settings under properties (when right-clicked on the browser icon) to deny read/write privileges to the file.
However, is there a much simpler process to do so; in case the user(s) decide to install other browsers by a USB device, internet access will not be possible.
