I have just bought a server to run my exchange 2003. Originally I was going to retire the old server but have now discovered that I have a second exchange 2003 licence so could actually run 2 servers.
My network is quite small (70 users on a single domain) so I have no need for 2 servers from a performance point of view. However the idea of increasing our redundancy does appeal to me.
Unfortunately i have no experience of running 2 exchange servers. Can anybody give me a brief overview as to how the servers would interact and give me an idea as to the best way to have them configured so that we could get up and running again as quickly as possible if either one went down.
