Question

IE 8 - There is a problem with this website's security certificate

Asked by: cpadm

I have an intranet website on my antivirus server, which hosts the McAfee ePO server GUI, but everytime I open the website, I get a security message:

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

I have added the website to both the intranet and trusted sites security groups, but I'm still getting the stupid warning. How do I make it go away?! 

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.
- The security certificate presented by this website was issued for a different website's address.
 
Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.

Whe you get this message then in left upper corner u will see info abou cert.
Import it, and this should solve you issue, or change policy of IE8

Trusting the certificate (or the root certificate if it was issued by a CA) is half of it as pointed out above.  You can deploy this as a trusted root certificate to your clients.

You also need to change how you are typing in / accessing the web site by name.  You need to look at the certificate's Issue To field to determine the correct name for accessing it.

For example:
you type in https://server1
the cert is issued to server1.domain.com

The names don't match - you need to go to https://server1.domain.com

Same thing if accessing by IP address, etc.

You can choose to continue then double click the gold padlock to view certificate details to check out the cert properties above.

Because I've already added the website into my trusted websites and intranet websites, there is no golden lock in the address bar to select.

I can open the webpage, but only when I click on the "Continue to this website (not recommended)".

I had imported the certificate into my trusted certs, but there was still an error - IE 8 didn't trust the Certificate Authority "Orion_MyAVServer_...", so I also imported this certificate into the "Trusted Root Certificate Authorities\Local Store", but every time I open the ePO website I get a different certificate error: "Mismatched address".

It turns out that the McAfee ePO application shortcut points at IE 8 and requests the following to open "https://localhost:8443/core". Of course this doesn't match the server certificate name as "My_AVServer" is not equal to "localhost". I edited the properties of the ePO web GUI shortcut to point at my server's name instead of localhost, and the issue was resolved.

Thanks for your help chaps,
Fin
