    Internet Explorer Blocked this website Certificate Error

    Hi All

    Can anyone shed some light on what might be causing this issue.

    Some websites youtube for example display Internet explorer blocked this website from displaying content with security certificate errors

    I am using IE9 (dont ask)

    cant pin it down to whats going on

    Do i need to push out an update for root certs via wsus if so whats the KB

    not displaying the error in the odd xp clients we have on IE8


    The time on server and clients is correct and synced.

    It must be something to do with the Zones but not sure what option to change Any help would be appretiated.

    tried installing the certificate from the site but makes no difference

    Do you do ssl interception? And/or using a proxy?

    yes we use a proxy provided by the YHGFL

    next test i was going to do was use my phone to connect to the internet bypassing the YHGFL connection to see if the errors come back

    Check the expiration on the SSL cert.

    looks like a problem with the smoothwall used by the yhgfl.
