I'm running a supported NCS 1.0 virtual appliance installation which functions fine for most folks, but Lobby Ambassadors with Windows 7 and IE8 or IE9 end up seeing an odd version of the NCS home page with all the graphs, etc, rather than the normal very restrictive list of guest users. Viewed with the same credentials with XP and IE7 or IE8, it's fine! Does not matter whether or not Chrome Frame gets installed. It's not as though the credentials are truly elevated, since the entire command bar is devoid of commands....it just doesn't show the list of guest users.
Yes I get this strange behaviour as well. I am using NCS-VA-18.104.22.168-small(1).ova appliance, However after having this happen on my Win 7 machine and opening in Firefox a couple of time it started displaying correctly in IE. But then when I got Helpdesk to login on their machine they had the same issue.
