How do I fix 'Error 403 Access Forbidden'?

Symptoms

You are unable to access normal web pages and are greeted with the error message Error 403 ? Access Forbidden / Access Denied.

Cause

This is caused by having incorrectly specified a proxy server in your Internet Explorer settings.

Resolution

To resolve this problem if using a broadband connection, you should remove the specified proxy from Internet Options by following these steps:

  1. Click on Start
  2. Click on Settings
  3. Click on Control Panel
  4. Double click on Internet Options
  5. Click on the Connection Tab
  6. Click the LAN Settings button and take the tick out of use proxy server.
  7. Click OK
If you are using a variant of Windows XP and cannot see a proxy specified in the Lan Settings, you may have to tick the checkbox (to use a proxy) and then access the Advanced button and remove advanced proxy entries. Once this has been undertaken, please untick the use proxy server box and close all Internet Explorer windows.

Netscape users should click on Edit > Preferences > Advanced > Proxies. Ensure that you have selected a Direct connection to the Internet.

If you are using a dial-up connection, then each setting specified is specific to that connection. This is the process to specify/remove proxy settings on a dial-up connection.
  1. Click on Start
  2. Click on Settings
  3. Click on Control Panel
  4. Double click on Internet Options
  5. Click on the Connection Tab
  6. Click on the dial up connection that you want to apply the settings to
  7. Click the Settings button on the right
  8. You can now click on Use a Proxy server and specify or remove the IP and Port used.
  9. Click OK. Click OK

More Information

If this does not resolve the issue, it is likely that you may be attempting to access a page which requires authentication. It is also possible, but not particularly likely, that there is a fault with the proxy (either transparent or one you have specified) which is causing this error. This can be checked by trying a different proxy and seeing if that one works.
