After installing KB3167685 on a locked down 2012 RDS server Internet Explorer 10 is having some issues with freezing.
When launching IE 10 adobeflashutil_activeX.exe also loads. IE will not fully load a page. The wheel will just spin and spin. Half the menu items are grayed out as well.
If I open another tab, both pages will load.
If I use taskmanager to kill Flash the page will load, but I have to kill Flash a few times.
If I disable the Flash add-on (Shockwave Flash Object) the problem goes away.
This does not happen to the domain administrator account as that account bypasses the group policy I use to lock down RDS.
My impression is that Flash is trying to process a command or configuration change but the GP is blocking it, but that is just a guess.
The policy is a loopback policy.
Any thoughts?
