∟Archived: IE 8 Displaying Certificate Error Page

This section provides a tutorial example showing that IE 8 fails to validate an HTTPS server certificate and displays a certificate error page.

Before continue to play with the HTTPS Website, https://login.yahoo.com, let me summarize what happened so far:

I removed root certificate "DigiCert High Assurance EV Root CA" using IE 8.
I removed root certificate "GTE CyberTrust Global Root" using IE 8.
IE 8 reinstalled root certificate "GTE CyberTrust Global Root" using Windows XP "Update Root Certificates" component.
I removed Windows XP "Update Root Certificates" component through Control Panel.

Now I want to see how IE 8 behaves, if I remove root certificate "GTE CyberTrust Global Root" again.

1. Open IE 8 and remove root certificate ""GTE CyberTrust Global Root".

2. Close and re-open IE 8 to visit "https://login.yahoo.com".

3. IE 8 returns with a certificate error page:

Certificate Error on IE 8 — Showing Certificate Error on IE 8

4. Read the error message:

Certificate Error: Navigation Blocked
There is a problem with this website's security certificate.

The security certificate presented by this website was not issued by
a trusted certificate authority.

Security certificate problems may indicate an attempt to fool you or
intercept any data you send to the server.

We recommend that you close this webpage and do not continue to this
website.

I am happy to see that IE 8 fails to validate "login.yahoo.com" certificate as I expected.
