I am not really understanding this. I thought you previously meant to set up another Local Area Connection icon on his laptop because his current config. called for "use proxy server" and automatic set up on router would not happen at home. Therefor he would need another config so that he could switch to it for "automatically obtain IP address". I cannot see why he would need to set up another user account on his laptop as he is the only user.
Bear with me if I'm slow
