SCCM 2012 R2 - Reporting Services Point installation - "The Datasource does not exist"

Question

Hi all,
Quick bit of background, we have SCCM 2012 R2 installed on a Windows 2012 R2 server. We have the SQL back end off box, configured on a SQL 2012 R2 server running on a Windows Server 2012 R2 cluster. Then there is yet another server which runs the reporting
services. I've just tried installing the Reporting Services Point on the srs server but it doesn't appear to have worked that well. Here's the info i've got back: 
A] Site Status > Reporting services point:
SMS_SITE_SYSTEM_STATUS_SUMMERIZER
Site System Status Summarizer detected that the availability of the "Reporting services point" role on server "\\NA-SQLR01.in.tna.local" has changed to Failed.
B] The last message from the SMS_SRS_REPORTING_POINT Component Status is "Site Component Manager successfully installed this component on this site system"
C] Here's the first chunk of info which appears in the srsrp.log file:
SMS_EXECUTIVE started SMS_SRS_REPORTING_POINT as thread ID 4204 (0x106C).
This is a SRS Reporting Point Role as SRSRP registry key exists.

Has anyone come across this issue before? Must admit, I'm not too hot on the sql side of things so any advice or suggestions would be greatly appreciated. Thanks in advance!

Answer 1

Hi guys, cheers for the swift response.
Garth, i can access SSRS in IE from the SCCM box and it looks a-ok.
Paul, nope can't say I've done any configuration of reporting services - the whole thing has been set up by the database team. Having had a trundle through Reporting Services Configuration Manager, it seems the Database team have set up SSRS in line with
the walkthrough you posted.
Since i'm not seeing the ConfigMgr_XXX folder appear in SSRS I'm wondering if there's something preventing SCCM from being able to create it. The message
"Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions
granted to user 'NT AUTHORITY\SYSTEM' are insufficient for performing this operation" sounds like the account SCCM is leveraging to perform the install might not have the right permissions in SSRS. Do i need to delegate specific rights to the NT
AUTHORITY\SYSTEM account in SRS perhaps?
