I am using .NET Framework 2.0 w/updates

I'm using WUD 2.23 beta842. I use a proxy (ISA server) with the following settings: Address: proxy.server1.com (private) Port: 80 Use authentication: yes Username: MyDomain\MyUserName Password: ****** When I click download the window closes and another opens. Then popup a message: Title: Windows Update Downloader Message: Errore del server remoto: (407) Richiesta autenticazione del proxy.
