going to go against the grain here and slightily disagree with trevor.

i agree that all small businesses should have a server, with disk mirroring, etc, but i also see businesses point of view that until they reach 5 users + then its very hard to find the cash for such a move.

i agree if they find a good local IT company it is a good investment but thats not always easy. and even with sbs's wizards most will need quite a bit of support.

if a peer to peer network is used correctly, where one machine is allocated to be the data storage machine, it can serve the one man band quite well when he progresses to his first few employees.
