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,
Sam Lester (MSFT)

    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

    Thanks Sam.. Same problem with me.

    I was trying to connect SQL Reporting 2016 from SQL Server 2017 Reporting Services Configuration Manager and was getting below error. Once connected with SQL Server 2016 Reporting Services Configuration Manager, it was solved
