Internet Explorer assigns all websites to one of four security zones: Internet, Local intranet, Trusted sites, or Restricted sites. The zone to which a website is assigned specifies different security settings that may lead to different behaviors. Following domains allow you to test the browser labs in different security zones in IE. Before navigating to following domains, you need to either map these domains into the correct security zone manually or run following command to map these domains automatically.
The HTTP error logs are stored in the c:\Windows\System32\LogFiles\HTTPERR folder. You can either compress the entire directory to retrieve all the HTTP error logs, or you can select logs based on their file modification time to obtain logs from specific time periods you are interested in.
