This error comes when we try to configure Reporting Services 2008 with
Reporting Services Configuration Manager. The reason for this is funny and identified as a known issue; It checks for wrong instance name. This has been fixed with the
Cumulative Update Package 3.
If you are unable to download, another method has been given with
this which I used. It gives instructions for changing the
reportingservices.mof file.
same problem was resolved after removing WMI components from old SQL installs.
