I'm trying to make a new federation trust, but it's not connecting to Microsoft's servers. I've done the same thing in my lab and it worked fine. In production, I get the following error. Does anyone know what connectivity is needed? I have IE working
through a proxy and the winhttp function set correctly, too.
