title: SSRS Subscription Failure - An error occurred during rendering of the report
body: <p>I have created a subscription that will place a report on a file share. When the subscription runs to build an excel file and put it on the shared drive, it gives the following error:</p>
  
  <pre><code> Failure writing file [Report Name] : An error occurred during rendering of the report.
  </code></pre>
  
  <p>When I looked in the logs I saw a little bit more detail, but it didnt mean much to me, as I am new to SSRS development.</p>
  
  <p>Here is what i am getting:</p>
  
  <pre><code> An error occurred during rendering of the report. ---&gt; 
   Microsoft.ReportingServices.ReportProcessing.UnhandledReportRenderingException: 
   An error occurred during rendering of the report. ---&gt; 
    Microsoft.ReportingServices.OnDemandReportRendering.ReportRenderingException: An 
   error occurred during rendering of the report. ---&gt; 
   System.IO.IsolatedStorage.IsolatedStorageException: Unable to determine the
    identity of domain.
  </code></pre>
  
  <p>What doesnt make sense to me is that I changed the file type on the export to CSV and it will export.  What is even more shocking is that the CSV file is bigger than the excel file (i was able to do a manual export through the UI for the report.)</p>
  
  <p>Any ideas on what is going on and how I can resolve this? </p>
  
  <p>Thanks,</p>
