title: IIS file download hangs/timeouts - sc-win32-status = 64
body: <p>Any thoughts on why I might be getting tons of "hangs" when trying to download a file via HTTP, based on the following?</p>
  
  <ul>
  <li>Server is IIS 6</li>
  <li>File being downloaded is a binary file, rather than a web page</li>
  <li>Several clients hang, including TrueUpdate and FlexNet web updating packages, as well as custom .NET app that just does basic HttpWebRequest/HttpWebResponse logic and downloads using a response stream</li>
  <li>IIS log file signature when success is 200 0 0  (sc-status sc-substatus sc-win32-status)</li>
  <li>For failure, error signature is 200 0 64 </li>
  <li>sc-win32-status of 64 is "the specified network name is no longer available"</li>
  <li>I can point firefox at the URL and download successfully every time (perhaps some retry logic is happening under the hood)</li>
  </ul>
  
  <p>At this point, it seems like either there's something funky with my server that it's throwing these errors, or that this is just normal network behavior and I need to use (or write) a client that is more resilient to the failures.</p>
  
  <p>Any thoughts?</p>
