title: FTP response codes
body: <p>I am troubleshooting Microsoft's FTP server (IIS 6.0) at a client site.  In the FTP log, there's a few response codes that I'd like to know the meaning of.  </p>
  
  <p>For instance, in the line:</p>
  
  <p>12:01:15 10.4.152.122 [194326]created x.jpg 550 1450</p>
  
  <p>I'd like to know the meaning of 1450. There's other ones as well, like 550 2, and 550 32.</p>
  
  <p>Anyone know of a site or reference that has the meaning of these sub-codes (not sure what the correct term is)?   </p>
