I've just started a new job where they caught wind that I'm good with computers. While setting up a plotter for them, I discovered all their PCs are running Windows 98. I asked about backups and they said they don't do any, although they know they should. One of the managers said he would quite like a server so that he could access documents while he's off site. I know almost nothing about server operating systems.
Would Windows Server 2003/2008 be suitable for a network with 4 or 5 PCs? Is it easy enough to pick up on and learn? Would it be a waste if I don't go into the detailed settings? What kind of hardware would be needed for the server and for the thin clients? Is there an alternative to let them easily browse their files remotely? I suggested a NAS sort of as a backup, but can they be accessed over WAN? I know Vista and W7 have a remote acces feature built in, but they would need more expensive hardware than a ~£100 XP machine.
