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]"

The IIS 6 WMI Compatibility Role service needs to be installed on the CAS server to allow MessageStats to determine the IIS Log File Path

WORKAROUND 1:

If Using MessageStats 6.8.1 Or Later Install the IIS Management Scripts and Tools Role Feature on the CAS Server:

1. Open Server Manger on each Client Access Server
2. Expand Roles and select Web Server (IIS)
3. Scroll down to the Role Services section and click Add Role Services
4. Under Management Tools, install IIS Management Scripts and Tools
5. Once the role have been added, rerun the IIS Log \ Owa gathering

If you are gathering against Exchange 2007 the IIS 6 WMI Compatibility Role service is still required.

If Using MessageStats Prior to Version 6.8.1 Install the IIS 6 WMI Compatibility Role Service on the CAS server:

1. Open Server Manager
2. Expand Roles
3. Select Web Server (IIS)
4. In the right hand pane scroll down to Roll Services and confirm the IIS 6 WMI Compatibility Role service is not installed
5. Click Add Role Services
6. From the Select Role Services wizard check IIS 6 WMI Compatibility
7. Click Next
8. Click Install

WORKAROUND 2:

Manually enter the IIS Log File Path in the MessageStats console:

1. Expand Exchange Organizations | Your Organization Name | Servers
2. Right click the CAS server that the IIS Websites task is failing against and select Properties
3. Select the IIS Log Folder tab
4. Click Add
5. Enter the full UNC path to the IIS Log Files in the following format:
   \\<CAS_servername>\C$\<folder_path

Please note: the drive letter in the UNC path needs to be in the format of an Admin share (C$, D$, etc)
