Im helping to setup and find the best server for my dads small business of 5-10 users. The functions will be primarily to store all the files and user accounts on the server and adding print devices. We have identified the HP Proliant Microserver with a few custom upgrades to be a good choice at around £400, however the Windows Server 2008 license seem to be over £500, is this right, as it is a lot of money just for a small business, or is there a cheaper/free version of it? A unix OS could be an option as i use linux myself, but my dad would have no clue on how to use it so Windows is a preferred option. Also im confused as to what the Client Access licenses are, do you need to buy one of these for every computer you wish to connect to it?
