I have an ASP MVC 3 website which is used on the intranet. It uses Windows Authentication and I’ve noticed sometimes on just a few user’s machines (they all use IE9), it just doesnt load and the user is presented with a white screen or “Internet Explorer cannot display this page” message.
I’ve set <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" /> in my <head> tag and I’ve also unchecked the box “Display intranet sites in compatibility mode” under tools > Compatibility View Settings in IE9.
I’m running out of ideas as to what is causing this issue. It’s intermittent too which is all the more puzzling. It works fine on everyone else’s machine (some even use IE9 and the rest use IE8).
Since you’re using ASP.NET MVC3, I’d strongly recommend installing Glimpse. It’ll help you see what’s happening on the server when the requests fail. Granted, you’d probably want to configure it to require authentication, but it can also be turned on and off in the web.config if you just need to it be available temporarily.
