 Looking back at your older posts it seems your
 proxy requires a
 password.  I have no idea
 how the configuration script sets up things
 for you, but apparently it bypasses the
 registry settings that it would
 normally
 use.

 Setup.exe supposedly should
 ask for that information via a dialog box
 when the proxy indicates it needs it, but it
 seems that your proxy just
 doesn't
 return the required 407 response header.  If you could
 figure
 out (via wget most likely) what the
 communication with your proxy looks
 like
 (with and without password) that might lead to somewhere.


I finally observed wget fail because of authentication, then work when given user, password. 
Screen output is below.
Subsequent wgets work without giving password, so there is some caching of authentication, 
apparently, at least for wget (and apt-cyg).
Setup is not as lucky, is unable to get setup.ini, and never asks for user, password.
It also only lists the download site I last used.
