WebClient.UploadFile error (2nd post)

[Saverio Tedeschi]

Hi all gurus, forgive me if I submit a 2nd post, but I'm no more able to see
my question. So:
I wrote an Win app with embedded FTP client (well, made some cut and paste
from others' projects :-)) to receive and send files from within the app
itself. Now the server I connect to (IIS 5, W2K Svr+SP4) from 1st Jan on
will allow just
http/https connection, so I can no longer use FTP. I've thought to use
System.Net.WebClient class and DownloadFile/UploadFile method, but when I
try UploadFile only obtain a message, described later in detail, while
download goes well. Can pls some1 point me to the right direction? How can I
enable POST on IIS, if this is the problem? TIA

Error message follows:
