So we are having an issue getting pass through credentials to work when access the domain website for our EOC platform. We can access via https://(servername), but not through website.name . We have recently gone through an in place upgrade (to the same server version and build) to fix some issues we were having with the server taking windows update. We are still using the same certificate that was issued before the in place upgrade. My research isn't coming up with a definitive answer, but does a new certificate need to be issued if the IP and server name remain the same? Or has anyone gone through something similar and I'm missing a key configuration after doing the in place upgrade?
