I assume that you're using the purple (or blue) CD labeled "Reinstallation CD Microsoft Windows XP Professional". When you place it in the CD drive does it autorun; i.e., popup the Windows XP Professional setup screen? Personally, I usually copy the entire XP CD to a folder on my hard drive, such as C:\XPHMSP1. I then use the second option, ''I want to specify my own local Windows share". It makes things go a little faster.
