Powerview Icon in SharePoint 2010

So you got PowerView installed and configured for your SharePoint 2010 instance.  You finally have figured out how to create a data source and you create your first report in a document library.  You click save and return to said document library, only to find the hideous blank icon next to the report instead of the PowerView icon.

I can help you fix that, and its really easy!

On each of your WFE's (web front ends) make the following change:

1. Verify that this file exists: C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES\ReportServer\16reportx_sp.gif
2. Open C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\XML\DOCICON.xml with your favorite text editor (Notepad++ is my favorite)
3. Add the following line directly beneath the entry for rdl extensions:
   <Mapping Key="rdlx" Value="ReportServer/16reportx_sp.gif" />
4. The final file should look something like this:
   
5. Save your changes.
6. Perform an IISReset.

Now, refresh you browser and you will see the PowerView specific icon.

 Hopefully this was a big help.  Leave a comment letting me know your experiences.
