Hello, I reinstall SQL 2012 SP1 Reporting Services on a remote server ( Win server 2012 ), pointing to the old database ( the old SQL server was a MS SQL 2008 R2 SP1 CU6), everything works well.
I also re-add the new SRS server from SCCM console, choosing “Create Site System Server”, again everything works okay. Now, from the Status Message Viewer I receive the following message: “The SQL Reporting Services datasource on Reporting point server "SRSserver.domain.local" is missing or has been changed outside of Configuration Manager. It will be rebuilt based on the RSP configuration.” Both http://srsserver/ReportServer and http://srsserver/Reports/Pages/Folder.aspx works great. I cannot find any info about this.. Thank you. Cheers.
