Wireless and Wired connection settings

I have a new laptop and I am trying to use it on both my home workgroup and office LAN. Can anyone tell me how to configure it so that it retains the settings for both my home "workgroup" and office "Domain" settings. When I switch between locations I have to manually change between workgroup and add it on the domain depending on location. At home I use wireless and in the office I use 10/100 wired. I am using XP Pro and have hardware configurations set for wireless and wired communications.

Thanks for any assistance.
