Certificate cannot be verified up to a trusted certification authority?

Digital Certificates SSL Certificate
1

I just installed a Comodo Instant SSL cert on my (iis 6) server. When I navigate to a secure page for that site, I get a security warning: “The security certificate was issued by a company you have not chosen to trust…”

When I view the cert, the certificate information shows “The certificate cannot be verified up to a trusted certification authority”.

How do I resolve this?

Thanks,
Pete

Never mind.
It looks like the problem may have been that I didn’t have the ComodoSecurityServicesCA.crt or GTECyberTrustGlobalRoot.crt installed on the server.
Once I installed those, the warning went away.

I am also getting this message on my website. I looked through the Installation instructions and didn’t see anything that we might have missed. When I view the certificate on the server (through IIS), it says “Windows does not have enough information to verify this certificate”. And if I look at the “Certification Path” tab, it says: “The issuer of this certificate could not be found.”

Any help would be much appreciated!
Thanks,

Hi,

If the intermediate certificates are not installed then you will see the message:
“Windows does not have enough information to verify this certificate”
and the certificate path will not be complete to a trusted root certificate.

So, you will need to install all of the certificates that were sent.
