Thanks for all the info guys. I found this in the article on microsoft's site that was suggested:
"You cannot create mirrored volumes or RAID-5 volumes on Windows XP Home Edition, Windows XP Professional, or Windows XP 64-Bit Edition-based computers. However, you can use a Windows XP Professional-based computer to create a mirrored or RAID-5 volume on remote computers that are running Windows 2000 Server, Windows 2000 Advanced Server, or Windows 2000 Datacenter Server. You must have administrative privileges on the remote computer to do this."
This would explain more clearly what the author of the book was trying to say and makes alot more sense now. Thanks for the quick feedback though!!
