With XP and 8 you need to have the networking group changed to homegroup. I believe that it's called 'workgroup' in XP.That needs to be changed to homegroup as it is called in 8. Don't have password protected on. If you have Silver-light check this out, link, I know it's for 7 and XP but similar to 8. Hope that helps.
