Can't display CR Charts on Server

Question

Hello,
I've created a number of reports that all run fine on my local machine and all is fine on the server except that reports with a Chart do not display. The CR toolbar and treeview pane are rendered but the chart shows up as a blank image or an "X".
I'm using Crystal Reports that's included in Visual Studio 2008. I'm running Windows Server 2003, IIS 6.0 and I've run the CRRedist2008_x86.msi installation file. All of the appropriate files are in wwwroot\aspnet_client. I've given both the asp_net and Network Services users full control of the c:\Windows\temp folder and I've entered the following into web config:
<appSettings>     
     <add key="CrystalImageCleaner-AutoStart" value="true"/>
     <add key="CrystalImageCleaner-Sleep" value="60000"/>
     <add key="CrystalImageCleaner-Age" value="120000"/>
</appSettings>
<httpHandlers>
     <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler,            
     CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/>
</httpHandlers>
</Handlers>                         
     <add name="CrystalImageHandler.aspx_GET" path="CrystalImageHandler.aspx" verb="GET"                
       type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=10.5.3700.0, Culture=neutral,           
      PublicKeyToken=692fbea5521e1304" preCondition="integratedMode"/>
</Handlers>

Any help would be greatly appreciated!

Yes, I have taken the steps in the suggested article that were specified for the VS 2008 version of CR. 
Strangely, we've discovered that reports with a chart are rendering just fine on computers that are on the network with the server. My development machine is not on the network and I get the "X" or missing image file where the chart should appear. However, when running the code locally I can see the charts.
Could this have to do with printer drivers?
Is it possible that there is a permissions issue when CR attempts to createthe CrystalImageHandler.aspx file? Where does crystal try to write this file and where is the .png image file created?
Thanks,
Rob
