I can't seem to find the answer for this through google, so hopefully someone here can help me out.
I have a wildcard certificate that is about to expire in 9 days. I received a new certificate from the CA that will expire in 2012. I installed the certificate in the personal certificate store. So I now have both certificates in there.
I created a new test website with the same ip address as the other sites, but gave it a different host header. I applied the new 2012 certificate to this site. So far so good.
If I go to the site in IE, click the lock icon, click on view certificate, it shows the 2010 certificate.
If I delete the 2010 certificate, the site stops working, even though the server still shows that the site has the 2012 certificate installed.
I have been working on this for days and can't seem to figure this out.
Has anybody else had this problem before? Any ideas on how to fix this?
