Have you ever needed to install multiple instances of SSRS, with each instance “connected” to the same instance of the SQL Server database engine? (By “connected”, I mean that the pair of [ReportServer] databases for each SSRS instance would all reside on the same instance of SQL Server. And each SSRS instance would be reporting on data from one or more databases that also resided on the same instance of SQL Server.)
To my surprise, I don’t see much guidance for this scenario on the internet. TechNet has an article. It’s consistently one of the first search results I get back for variations of “Install multiple instances of SSRS”. That article (and a few others) omit a simple installation step/requirement that was a blind spot for me. (More on that towards the end.) I finally figured out what I was doing wrong and eventually succeeded with my task. Let’s walk through the steps.
I’m not quite positive what problem this best solves, but that could just be a lack of vision on my part.
