In previous versions of IE one could "non-destructively" append trusted sites to systems by using a adm, preserving a users existing trusted sites. This does not seem to be possible in IE8. I have tried adding using registry preferences. Maybe I am just missing a step. any Ideas? I have tried this approach http://www.energizedtech.com/2009/07/managing-trusted-zones-with-gr.html which seemed plausible but the technique did not work on the domain. The registry entires were present but IE did not intrepret them and the sites were not recognized as trusted. -- Suggestions Appreciated
