Are you using a CERN proxy? WININET, the system DLL that actually implements the CFtpConnection object for MFC, turns out to not support FTP connections through CERN proxies.

You _can_ get the connection to work through the proxy, though; you'll have to use the INTERNET_FLAG_RAW_DATA flag in the dwFlags parameter.  The technique you'll need to use is documented in the Microsoft KnowledgeBase.  Please see the article at http://www.microsoft.com/kb/articles/q166/9/61.htm
