right a few months ago i asked about this and the situation has slightly changed so i'm starting again.

at work i need to setup a server pc that will have all of our files stored to serve around 5 or 6 pcs, needs to run somesort of mail app, so that we can share contacts/calendar items etc through outlook. also ideally needs to be used as an ftp and web server.

basically what do i need for this in the way of software and hardware?

not too up on windows server or exchange but i think it may be the only way, they do look terribly difficult to set up though.

any help is very much appriciated
