ClickOnce Deployment Error: "Proxy authentication required" - Fix available

Are the accessing machines configured to use a proxy server that requires authentication?

If you answer both questions with YES: then you found a bug.

The good news is - there is a solution. You can request a fix (free of charge) at a Microsoft support holine and it will be (e-)mailed to you:
