Hi All,
I have written a program to create web pages and I want to ftp the finished page tp the web server when they are finished.  The code hangs up on this line
       Dim clsStream As System.IO.Stream = clsRequest.GetRequestStream()
with the error message...

System.Net.WebException was unhandled
  Message="The remote server returned an error: (550) File unavailable (e.g., file not found, no access)."
  Source="System"

The web host is hosting two domains so I need to choose which one the file goes to, hense the line
        DirectCast(System.Net.WebRequest.Create("ftp://" & s1 & "/" & s1), System.Net.FtpWebRequest)
where the first s1 is the domain name and the second s1 is the directory for the domain.  They just happen to have the same bane.  It appears the program is making a connection with the server but for some reason not accepting the file upload.

Can anyone tell me whaat I am doing wrong?
 
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
        Dim s1, s2, s3, s4 As String
        ' set up request...
        s1 = Form1.TextBox3.Text
        s2 = Form1.TextBox1.Text & "\" & Form1.TextBox14.Text
        s3 = Form1.TextBox4.Text
        s4 = Form1.TextBox5.Text
        Dim clsRequest As System.Net.FtpWebRequest = _
        DirectCast(System.Net.WebRequest.Create("ftp://" & s1 & "/" & s1), System.Net.FtpWebRequest)
        clsRequest.Credentials = New System.Net.NetworkCredential(s3, s4)
        clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile
 
        ' read in file...
        Dim bFile() As Byte = System.IO.File.ReadAllBytes(s2)
 
        ' upload file...

        Dim clsStream As System.IO.Stream = clsRequest.GetRequestStream()
        clsStream.Write(bFile, 0, bFile.Length)
        clsStream.Close()
        clsStream.Dispose()
    End Sub
End Class

Do you have access to the ftp servers logs?  You may want to install something like wireshark (http://www.wireshark.org) and do a packet capture from your computer to verify what you are sending out.

The 550 error message means you are attempting to write to a directory that you either do not have permission to write to or does not exist, it can also mean you are attempting to over write and existing file that you do not have permission to write to.

One problem could be that the ftp server and web server have a different default starting location.
