Multiple laptop profile in Domain

Hello All; I need to know how to set up a laptop with 2 connection profiles, my main objective is to set up a laptop to use a static IP address when the user is in the office, but since the computer is also used at home I want the laptop to be able to use whatever dynamic IP address it can get from their home ISP. The laptop is part of a Windows 2003 Domain, laptop is running windows XP pro SP2.

Can anyone help me achieve this.
Thanks in advance for all your help.

Thanks
CG._
