How do you investigate the certificate error "This certificate cannot be verified up to a trusted certification authority"

Posted on 2009-12-24

When we utilise a specific website we notice that there is a certificate error displayed.

When we click on it and choose view certificates we are presented with a new certificate window and the general Tab displays "This certificate cannot be verified up to a trusted certification authority" (Please see the attached image).

What do I need to do to correct the problem.  As its dealing with a banks website, its important that this mechanism works for piece of mind.

Thanks for your help

    I would contact the bank...maybe Darren who per the snapshot seems to control it!
    In Internet Explorer if you click on Tools ,Internet Option, Content, Certificates,
    You will need to add VeriSign Class 3 Secure Server CA into the Intermidaite Certificate Authorities.
    I have attached an exported copy of mine but had to change the ext from p7b to txt, to get it to be allowed to do so.
    Just import this into the above Intermidaite Certificate Authorities. And it may resolve your issue.

    Thank You.

    I imported the certificate you generously supplied as suggested and the certificate error has dissapeared.

    On this occasion you happily supplied me with a copy of a certificate, but is there a specific way for me to obtain the certificate automatically or download it from Verisign?

    This one lasts for a long time , but there may be others that crop up and I won't be able to call on you for all of them.

    Ideally I would like to fix the route cause if possible.

    Thanks for your help.

    Sorry I haven't replyed sooner past few weeks have been hectic...
    A Certificate is issued to subscibers as a way for them to assure that content or data is from a legitimate source. So you usally will need to get a certificate from the issuer that is using that certificate to ensure you that the transaction or information being provided is confidential between the using parties.
    The Magority are provided by Microsft to ensure the O/S and Applications on your PC are safe from Compromise. So keeping your system updated with Microsft's latest releases is the best way to ensure your certificates stay functional and to get them working again if they stop working or expire.
    In the above screen shot besides the IMport feature you used there is also an Export hich I used to provide you a good copy of that certificate. If you have Very important certificates I would strongly suggest you export copes of them and keep them in a safe place as a backup so you can restore then with import should anything happen to those certificates.
