We are a small business with 6 computers networked to a server running NT 4.0. We also have an off-site location with 3-4 computers that are not currently networked at all. We need to access info between the two locations and also need to access e-mail off-site. Is the SBS 2003 the right option for us? We would like to share calendars and files between the 2 locations and I'm thinking that Sharepoint could manage this for us. I know that we need to be running XP Prof to be able to access desktops, but can pc's not running XP Prof still use Sharepoint? Is there anyway to upgrad our existing server or do we have to migrate to a new one? If anyone has some input on this, it would be very helpful.

Thanks!
