We're setting up HTTPS for all our websites. Unfortunately I'm not really experienced in IIS.
I have two certificates, one is a EV-UCC-Certificate with 10 subdomains included. the subdomains are from two different domains like this:
I also have a wildcard certificate for one of those domains
both domains run on the same IIS Server under the same IP Adress.
When I assign the wildcard certificate to some of my sites, everything works fine but when I then want to assign the EV-UCC certificate to another site which is in the same "sites" collection in IIS, I get the following error
At least one other site is using the same HTTPS binding and the binding is configured with a different certificate
I'm a little confused by this. Why can't I assign two different certificates on the same IIS? Can only be one SSL-Certificate on an IIS? If so, is there a workaround to make IIS think he can carry two SSL certificates?
I'm running IIS 7.5 on Windows Server 2008 R2
