In our organization, when users run up against the firewall in Internet Explorer, this is what they see:
The classic IE "Page Cannot Be Displayed".
Of course, this is also what you see when it's the external site having problems.
Is there any way for the user to determine if it's firewall-related or server-related? Anything in the Dev Tools of IE?
I don't mean any specifics of the firewall, just as simple as finding out "This page cannot be displayed because firewall, or not because firewall". Nothing more than that.
