We have a single server running 2003 with Exchange. We stopped using exchange a year ago when we moved to Google mail and all of our apps are in the cloud. It's only used as a file server these days.
It died over the weekend. Motherboard failure.
What options do I have? Is a NAS box practical for an office with 20 computers (all running XP Pro on a single domain). We'd only need rudimentary permissions. What happens to all the clients that will still think they're part of a domain without a DC?
