I retired a management server – now SCOM reporting doesn’t work?

When you first install reporting, you have to supply a management server.  This is used for SDK based connections that SCOM reporting requires.  If you ever retire this management server, reporting will break so this is an additional step to ensure you check whenever you retire a MS.

There are three places you need to update to a new management server:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\System Center Operations Manager\12\Reporting\DefaultSDKServiceMachine

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Reporting\DefaultSDKServiceMachine

and TWO places in the file:

rsreportserver.config on your SSRS server path similar to:  \Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer

(You could always just uninstall SCOM reporting and reinstall it somewhere else…. but that would be a bit drastic, don’t you think?)
