I was getting mad in configuring our internal report servers exposing them to internet on https using our CA.
Everything was ok using the reporting services web-server (I was able to navigate and invoke all the reports) but it was impossible having the report manager application working.
The problem was that the DNS names (obviously) were different from netbios name and I’ve found this article that solved my problem:
This is gold!
What is surprising is that in any real world scenario you will find a DNS name different from the internal, why I need to hack the registry to deploy my configuration?!
PS: Remember to restart IISAdminService, an iisreset isn’t enough!
