This will be my first time (and hopefully last) that I install an ssl cert on iis6.

We have multiple different root domain sites hosted on this server, each with its own IP Address.

If I install a cert for say, example.com on IP Address 1, what will happen if a user tries to navigate to otherexample.org on IP Address 2 over https? Will the connection be refused, or will they be served the only certificate installed?

This is the thing about certificates. Everything about certificates must be correct and must match. Or there will be an error and it will not work. There are some exceptions - a wildcard certificate can match multiple names for a given domain name, but that is about it.

So no, connections to otherexample.org will fail. And I am ignoring that the other IP address is not bound to any certificate.

  • I don't understand. So even if ip address number 2 is not configured to use a certificate, connections will still fail?

  • That's the concept. When you configure a certificate in IIS, you are usually binding that certificate to a specific IP address/name.
