Connecting to SSRS through Management Studio throws “Invalid Namespace” Error


When connecting to a SQL Server Reporting Services instance through Management Studio, I encountered the following error:

SSRS Connection Error - WMI Provider Error

Report Server WMI Provider error:
Invalid namespace (Microsoft.SqlServer.Management.UI.RSClient)

It turns out that I was trying to connect to SSRS 2012 through SQL Server Management Studio 2014. Once I launched SSMS 2012, I was able to connect successfully, so it was a simple resolution to a somewhat confusing WMI provider error message.

Thanks,

    Is that when you try connecting to the servername\instancename? I have not had many problems connecting to the ReportServer web service URL.

    1. Hi Joie, yes, I was using servername\instancename in the connection string as opposed to the URL. I was running it on my test lab, messing with some different options and writing up the notes from our work today when I saw it. I don’t remember seeing that specific error in the past and didn’t find anything online with a quick search. I was surprised to see the issue being a down-level version issue (2014 tools connecting to 2012 instance) since that is typically solid functionality.

      Thanks,
      Sam
