Hi Paul:
Yeah, I agree- people tend to buy servers like they were buying Maserati's. If they have any limitations, it'll be with Jet 4 rather than with a server hosting the back-end tables.
Anyhow, WinXP Pro limit is 10; Win XP Home limit is 5 for peer to peer networking. This means the max Home will see is 5 other machines. Win XP Home cannot join a domain, either, plus it has a host of other restrictions (including restricted login permissions).
It's discussed here, for example:
http://www.computing.net/answers/networking/xp-network-size-limitation/23912.htmlNumerous other Google sites discuss this issue, although it sometimes seems to be like a needle in a haystack!
