I currently own three computers, but only have access to two (one was given to my girlfriend for her use). I would like to learn Server 2003, so here was my plan:
Install Server 2003 on the older PC, then use Virtual PC to create multiple virtual computers on the new PC. If I use Microsoft's Virtual PC, will I be able to network them together and apply AD and GP to them?

Or is it a smarter idea to purchase a new computer for this project?
