well it kinda depends, are you on a network with Exchange server.....if so, there is an option to allow or disallow access to the internet for specific users...that is the simpleist way.
If not, Im sure there is a way to do it in the Registery, but Im not quite sure, maybe someone else in here can tell you that.
There is also the option of the Policy editor, which works great as you can restrict all .exe programs and only allow which ever ones you think are necessary for the user to use, but it might be a bit much for just IE..... Jay~
