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.
Run CMD or PowerShell as an administrator and execute the following command:
SecEdit.exe /export /cfg security-policy.inf
You can find the exported file: security-policy.inf in the current working directory. For example, if you executed the above command in c:\temp, the file will be located at: c:\temp\security-policy.inf.
