We're setting up a small office on Windows SBS 2003. Although growth is expected, right now we have 2 workstations and 2 laptop users. The laptop users will sometimes be in the office (docking station) and sometimes on the road. Is a standard anti-virus suite with just multi-user license sufficient? How should I go about protecting the server? Suggestions as far as Zone Alarm, Norton, TrendMicro, etc are welcomed!
