We have added a new domain into our infrastructure which will host our portal site. Is there any way to centrally add this to the bypass proxy sites list and to the Local intranet zone list. I know its possible thru group policy but as i understand i will kick off any settings which the users have already configured already. What I am expecting the experts here to suggest is a way in which i can append the domain both of these lists centrally. There are about 5000 clients and doing it manually would not be an option. Group policy, web based scripts, login scripts etc..please advice.
