I am trying to run the Group Policy Results using the GPMC to report on GPO setting applied to Windows 2008 R2 servers. Whey I try to generate the report I get this error message:
"An error occurred while generating report:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"

It doesn't matter if I try this from another Win 7 or W2K8 R2 or run it from the console. I get the same error message.
