title: IIS sc-win32-status codes
body: <p>[Background]
  I have a code of 64 in my iis logs which I think are client disconnects whilst uploading large files.  I also get some ComExceptions with the same status code which I have gathered are pretty much the same issue.  Given the infrequency of these issues I've decided these are only to be expected and are not a problem but it did give rise to this question:</p>
  
  <p>[Question]
  Is there a list of possible win32 status codes somewhere; particularly the ones that can end up in IIS logs?</p>
