Q:

Problem connecting to SSRS reporting services

When I try to connect to my reporting services server (SQL Server 2005) from my local machine, SQL Server 2014 I get the error message below

Invalid Namespace (System. Management)

But when I RDP into my reporting services server and connect to reporting services there, everything is fine. 
There is nothing wrong with the reporting services. 
Is there a way to connect to SQL Server 2005 Reporting Services from a SSMS 2014? 

A:

I have the same problem except my Reporting Service is 2008 R2. 
Anyway I have SSMS 2014 on the server where Reporting Service is installed and get the same error. 
I have installed SSMS 2008 R2 and straight away it works. 
So you must have same version SSMS as Reporting service. 
And here is explanation:
In Reporting Services, the namespace for SSRS 2014 is root\Microsoft\SqlServer\ReportServer\RS_\v12\Admin
while the namespace for SSRS 2012 is
 root\Microsoft\SqlServer\ReportServer\RS_\v11\Admin.
