XP Profiles

I set up a new laptop with XP to resolve login issues for my boss on different networks and it is working great. No more turning winproxy on or off etc. This was done at work with his work profile. All the docs and spreadsheets he had moved to his hard drive are visible when he’s at work but he cannot see them when he logs in at home. How can I set up the profiles to see the hard drive the same way for each log in?
