I need some advice on server setup.
Currently we have 1 Small Business Server (AD, email, website, and FTP site are the main services running on it) 1 file server, and 1 Database server (Global Shop). We just had our SBS server crash 2 weeks ago and it took 3 days to get everything up and running again on a new server (many late night and ungodly amounts of stress). I would like to move off the SBS for obvious reasons (everything running on one server=very bad). I am thinking of moving up to 2-2000 Servers or 2003 Servers and a server just for Exchange. The 2 servers would be setup as 1 PDC and 1 BDC for replication of AD. I would also like to replicate the exchange server somehow (that is the main reason for posting). What I am looking for is more redundancy in the network so if one server goes down we have little to no downtime, especially for email.
I would like to know if I am on the right track or if I am in the clouds somewhere dreaming. I would also like to know how some of your servers are setup.
