title: How to obtain more information from SRCSRV?
body: <p>I'm working on a custom symbols/source server.
  I've been able to produce pdb files which reference our sources. The most of our sources can be retrieved by Visual Studio. But sometimes, SRCSRV fails to retrieve them.</p>
  
  <p>If I inspect the Visual Studio output window, I can get the following message</p>
  
  <pre><code>SRCSRV: Source server cannot retrieve the source code for file 'e:\SoftwareFactory\Projects\Product.Net Trunk\WorkingDirectory\Services\ErpWebServices\ErpServiceLegacyHost\Threading\ErpTransactionsSynchronizationContext.cs' in module 'C:\Program Files (x86)\Product\ProductCommon\ePgiStarterCS\server\Product.Erp.Services.LegacyHost.dll'. Données non valides.
  </code></pre>
  
  <p>The web server hosting the sources hasn't received any request for such file. So this must be an issue in the record concerning this precise file.</p>
  
  <p><strong>Is there any way to get more information by SRCSRV?</strong></p>
