Do you have a backend server? Did you look at the IIS request logs?

I get to the logon screen ok on the front end but once I authenticate, I get the Bad Request (invalid hostname) error in Firefox. In IE, I get webpage cannot be found, 400 error. I've check Google which points me to host headers or IIS configuration but none of it is helping. I'm just testing this internally at the moment by IP address. Help anyone?
