in the security tag of the IIS5 (the built-in with win2000) you have to change a key that says:

LEAVE IIS TO ADMIN THE PASSWORD TO CONNECT (or something similar).

It's a checkbox that appear checked. Just uncheck this and try to connect. Also realize if you can go in and out thru your adsl router (remember...router works as semi-fw and a route doen't allow see traffic behind itself).

Test if opening port 20 and 21 (ftp data and info connection) you can open an ftp session.

if not reply this mail.

Bye and Good Luck!
