I'm trying to disable IE9 ESC on my SBS 2011 SP1 install, but the instructions I find don't work. One set uses Server Manager and turns it off in the related settings pane on the right of the screen. My version of Server Manager does not have that pane. Another uses regedit and some CLI commands, but the CLI commands do not work on my machine ("missing entry"). Are there up-to-date instructions anywhere?

The linked file does not work for me. A search on the file name didn't turn it up either. Got a working URL?
