hello all. i am trying to create a small office network based on windows server 2008r2. i have bought myself a dell server which comes with foundation for 15 users... what i want to do is the following: create a pdc with simple shares with internet access (probably will use tmg) with speed limits on internet access for users. another thing i want to do which i believe is impossible without 3rd party software is when a user joins the domain i want them to keep their local desktop. most people will freak out when they see a new blank desktop provided by the server. what i have done so far is create a pdc and its working alright. still ironing out some issues. i want to now setup tmg on it and be able to speed limit the users for internet access (not network). any advise please?
