Fixing a 403 forbidden error requires permission to access the Windows host machine using the Internet Information Services console. The precise solution depends on why the 403 error occurs. The 403 forbidden error is an HTTP status code which forbids the user from viewing the page. The three most common causes for this error are empty html directories, no index pages, and permission or ownership errors.
The most common solution to fixing 403 problems is to simply check the URL for errors. Make sure the URL specifies an actual web page file name and extension and not just a directory. Most sites are configured to forbid directory browsing, so the 403 error results when trying to view a folder instead of a specific web page.
403 errors also result from firewalls or other security settings. If the URL is correct and the 403 error persists, check to see if the firewall is preventing access to any web pages. Visit the browser’s settings, and make sure cookies are enabled for the website in question.
Some 403 errors are unavoidable. Public or protected computers on school or company networks often block access to certain sites depending on the web page’s content. Working around these 403 errors are not possible because access is strictly prohibited through the network.
