title: Sitecore Media Library upload error
body: <p>I am a newbie to Sitecore 6.4. </p>
  
  <p>I tried to upload an image to Media Library/Images. However, the system always tells me "One or more files could not be uploaded. See the Log file for more details.". </p>
  
  <p>The error message is "IOErrorEvent type="IOError" bubbles=false cancelable=false eventPhase=2 text="Error #2038"</p>
  
  <p>I've assigned all the permission to sitecore\Admin, default\Anonymous, extranet\Anonymous.</p>
  
  <p>Did I miss anything?</p>
