Error 407 with Proxy authentication

Hi all,
Since my goal was to upload/download/list/delete from a remote FTP
server avoiding problems with Isa servers (only download and list are
allowed), I have just downloaded curl-7.19.4 (win 32) and

Trying this simple command:
curl -u DOMAIN\USER -x myproxy:Port

to get Google page testing the proxy configuration, I get the error
"Error code: 407 proxy authentication required. the isa server requires
authorization to fulfill the request. access to the web proxy filter is
denied (12209)"

Can you give me an hand?
