Error: "The IIS server does not contain any sources from which to gather data" (4225483)

The IIS Websites task fails with the following errors when gathering against Exchange 2007:

"The IIS server does not contain any sources from which to gather data"

"The following error occurred in trying to execute a given task: Quest.MessageStats.Runtime.MessageStatsException: Error in report pack data source execute ---> System.Exception: Exception of type 'System.Exception' was thrown. at IISLogsReportPack.qmsIISLogsProcessor.VirtualServerExpansion.Quest.MessageStats.Runtime.IReportPackDataSource.Execute() at Quest.MessageStats.Runtime.QmsCoreManager.Quest.MessageStats.Runtime.Interop.IQMSCoreManager.ExecuteTask() --- End of inner exception stack trace --- at Quest.MessageStats.Runtime.QmsCoreManager.Quest.MessageStats.Runtime.Interop.IQMSCoreManager.ExecuteTask()"

From the MessageStats console, if you open the properties for the server and view the IIS Log Folders tab there is no Log File Path populated. Clicking Refresh results in the error:

"The following error occurred while retrieving the IIS server properties. [Provider load failure]"
