Internet Explorer 404 error occurs when using proxy servers and after being blocked by Websense.In some versions of Internet Explorer I get a 404 error after being blocked by Websense. If I refresh the page, I then get a block page.When a connection is established through a proxy server, the host name of the site and the proxy server name are cached in Internet Explorer. On future attempts to access the host name in the same session Internet Explorer has cached information about which proxy to use. Therefore, all subsequent connections to the host are tried through the proxy that was used previously. This means that if the proxy server name that is cached is unavailable during the same session, the automatic proxy configuration script is not re-processed and you receive a "Page Cannot Be Displayed" error message in Internet Explorer.What is occurring is that the block page URL is being passed to the browser client, but the browser then attempts to access the Filter Service block page using the wrong port. For example, the block page's port default is 15871. The browser would mistakenly try to use port 8080, for example, to access the block page. Disabling proxy result caching prevents this issue and forces Internet Explorer to use the correct port as specified in the block page URL passed to the browser from the proxy.
Make Sure Proxy is Off
A proxy supplies internet data to your client if configured to do so. An upstream proxy proxy provides the Internet pages to your proxy.

Freegate starts in proxy mode by default. It will automatically open Internet Explorer and corrects all settings.After it has completed its set up process it will open the default website.
If using Internet Explorer: Select Tools, Internet Options, Connections, Lan Settings. If using another broswer, it can usually be found in that browser's network setup options.
Install free proxy software on your PC. Pay for access to a proxy server located on the internet. Set up an encrypted tunnel between the proxy installed on your PC and the proxy on the internet. Set your brower to use the proxy installed on your PC. Done.

If it's just one PC, you could block the MAC address from outside traffic on the router. You could also remove the gateway IP address on the PC. You could set a bogus Proxy server in Internet Explorer (that just blocks IE though)
