"This certificate has expired or is not yet valid."

    Yesterday, Internet Explorer 7.0 started to display the message of "This
    certificate has expired or is not yet valid." when assessing Comcast.net and
    Comcast support says that IE7 has "expired" and that I should contact
    Microsoft, which will not resolve this problem without 59$.

    What has caused this message copied below and how do I eliminate it?

    There is a problem with this website's security certificate.

    The security certificate presented by this website has expired or is not
    yet valid.

    I have Windows XP Professional version 5.1.2600 Service Pack 3 Build 2600 on
    PC with this message.

    I had accidently changed the Microsoft date/time yesterday, so I am
    rebooting now to see if it eliminates this message after correcting the date.

  4. Nonetheless, I'd still recommend going to Windows Update, select CUSTOM and
    scan. Install any Critical Updates offered (i.e., KB956390). If a Root
    Certificates update is listed in the Optional Updates category, install it
    to take full advantage of IE7's enhanced security.

    My computer is set to receive security & critical updates automatically. I
    ran Windows Update>Custom, as you suggested, and it found "No high-priority
    updates for your computer are available. To select other updates, use the
    options to the left."

    All is working fine now with date/time correction - wish that Comcast had
    this one in their FAQ.

  6. Root Certificate updates are Optional Software Updates, NOT high-priority or
    critical updates, and they are not offered by Automatic Updates or in the
    primary scan results at Windows Update.

    Thanks for pointing that out.

    By the way, does anybody know what that "Silverlight" thing is? Or has used

    As to your original question about the cert expiry, I see you found that the
    cause was the date. The browser compares the OS date against the certificate
    dates, and shows the warning if the cert appears to not yet be valid (start
    date in the future) or expired (expiry date in the past). Morale of the
    story - don't change your system date ;)

  10. Good for you. There's usually a new Root Certificates update released every
    2 or 3 months or so. Remember to check for a new one soon.

    Speaking of which, the one you just installed was released on 23 Sept-08 and
    according to http://support.microsoft.com/kb/894199, a new Root Certificates
    update is scheduled to be released tomorrow (25 Nov-08).

  11. The latest Root Certificates update is available now.
