500 'FEAT': command not understood

I'm getting this error "500 'FEAT': command not understood" when I try to connect to Windows FTP server. anyone can help?

same problem here.. Please add the ability to disable the FEAT command so connecting won't fail with windows servers running SERV-U.

Thanks for report. I'll make WinSCP to be able to handle negative response to 'FEAT' silently.
