I have successfully deployed a ClickOnce on our local intranet.  

When I deploy ClickOnce to our corporate web server outside of our network I
am getting an error that I have pasted at the bottom of this post.

If I install this on my computer at home from the corporate web server I do
not get an error.

The only other variable I can think of is we have a proxy server, but the
error message does not indicate that this is the problem.

Please help.
