Using the IE Content Advisor to block all Internet access
Posted By Chris Stinson in Security, Viruses, Trojans, Windows on March 12, 2009
This is an old trick that was documented on the Microsoft website for Windows 95 – Windows 2000 but seems to have disappeared since. Here’s a basic retelling of the procedure to block all Internet access and allow only approved sites using the FREE content advisor found in Internet Explorer.
1. Copy the following text into Notepad and save it as “noaccess.rat” in the Windows\system32\ directory (or another directory of your choice). Be sure that the file extension is .rat and not .txt. You can download a zip file containing noaccess.rat here.
(rating-system “http://www.microsoft.com”)
(rating-service “http://www.microsoft.com”)
(name “Noaccess”)
(description “This file will block all sites.”)
(category
(transmit-as “m”)
(name “Yes”)
(label
(name “Level 0: No Setting”)
(description “No Setting”)
(value 0))
(label
(name “Level 1: No Setting”)
(description “No Setting”)
(value 1))))
2. In the “Control Panel” double-click on “Internet Options” and click on the “Content” tab. If in Internet Explorer, click on “Tools” and “Internet Options” and click on the “Content” tab.
3. Click “Enable.”
4. Inside the “General” tab click on “Rating System.”
5. Remove all entries and click “Add.” Add “noaccess.rat” from the Windows\system32\ directory.

6. Click on the “Approved Sites” tab and add all the websites you wish to allow access to.

UPDATE (Dec 14 2009): I have added the noaccess.rat and noaccess.txt files to a zip file that can be downloaded here.
