When the internet explorer 404 error occurs?
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.

What is need for active network monitoring system?
1. You notice an unusual spike in TCP and UDP flows from a single internal source to multiple destinations. Describe in detail the steps you would take to determine the type of traffic that this represents. 2. You have observed TCP connections to an IP address. The HTTP connections return a file named a.txt but when you try to retrieve the file with your browser you receive a 404 error code. You do not know the DNS name associated with the IP address (there is no reverse map). Describe the steps you would take to retrieve a.txt. Provide a plausible explanation why another machine on your network is retrieving a.txt but you are not able to do the same. 3. You are presented with a list of known bad DNS names but are not allowed to monitor traffic with network sniffers. You are asked to indicate what names are in use on your network without using a network sniffer. Describe, in detail the steps you would take. 4. You receive a report that an attacker from the external Internet has connected inbound via port 443 to remotely control a host on your internal network but you know the firewall blocks inbound connections.
