Hi
I have a user who has been migrated from Windows XP to Windows 7 and is now having an issue with accessing one particular website which unfortunately is critical for their job.
The site requires a personal certificate to work and in Windows XP (IE8) this site is in the Trusted Sites Zone. When you access the site it pops up the certificate verification dialog asking the user to confirm its the correct certificate and when you hit ok, you can access the site.
On the new Windows 7 PC (IE8) the site is also in the trusted site zone and I have ensured that the same security settings for that zone are applied as we use for XP. The user contacted the website vendor who issued a new certificate which I can see successfully in the certificate store. When the user accesses the site, they get the certificate pop up asking to verify the certificate is correct (which it is), then when they hit ok, they get a page could not be displayed error.
I have contacted the website support team and all they have been able to do is verify the certificate is correct and then politely inform me that the problem is at my end which is no help at all :(
I have tried everything I can to ensure the Windows 7 and XP settings are identical yet the site still refuses to load on XP. The vendor is 100% certain the correct certificate is installed and I cannot think of anything else to troubleshoot.
I have even dropped the site into the local intranet zone which is even less restrictive than the trusted site zone and this also didn't help.
Is there some different behavior with IE8 Windows 7 and personal certificates than there is for IE8 on XP SP3?
Thanks in advance for any help.
