My client wants to use an FTP program I have written, but this isn't able to connect to the FTP server. I have several other users of this program and they don't have this problem. I'm running on Windows 7 and using the Microsoft routines InternetOpen and InternetConnect but the latter returns error code 12029 which suggests the password is wrong. And yet if I go into Internet Explorer I can connect to the FTP address and list the files on the server, though if from there I go to "Open FTP Site in File Explorer" I am prompted for the FTP details and it also fails.
Can someone tell me what is different about FTP on DreamHost so that I can modify my FTP program. Thanks.
