Hi,

We want to upload a file to a business partner using FTP with SSL from our
intranet. Our proof of concept solution in VB uses FtpWebRequest based on an
example at http://www.123aspx.com/redir.aspx?res=34336:

    Dim reqObj As FtpWebRequest =
WebRequest.Create("ftp://ftps.example.com:1742/123456789_12-31-2007")

    reqObj.EnableSsl = True
    reqObj.UsePassive = True
    reqObj.Method = WebRequestMethods.Ftp.UploadFile
    reqObj.Credentials = New NetworkCredential("username", "password")

    Dim streamObj As FileStream = File.OpenRead("D:\Files\123456789_12-31-2007")
    Dim buffer(streamObj.Length) As Byte

    streamObj.Read(buffer, 0, buffer.Length)
    streamObj.Close()
    streamObj = Nothing

    Dim reqStream As Stream

    reqStream = reqObj.GetRequestStream()
    reqStream.Write(buffer, 0, buffer.Length)
    reqStream.Close()
    reqStream = Nothing
    reqObj = Nothing

We are getting the error "Unable to connect to the remote server" on the
"reqStream = reqObj.GetRequestStream()" line. The username and password are
correct. What should we check next?

Thanks,

Dave
