We currently have a Domain Controller with Exchange Server installed. (Server1) we are currently setting up a new server, this again is a Domain Controller, this has been set-up in Sites and Services, has been set a Catalogue server, and DNS setup correctly. (server2) this server will be moving to another offsite location. (dataCentre) the two sites will be setup with hardware VPN. what we want to be able to do is setup Exchange on server 2, because all of the staff will be connecting into server2 as it has dedicated broadband. If server 2 is down or unreachable they will try server 1. We want exchange to be replicated from one site to another so it doesnt matter which server the user connects to it is still the same. We also want one server to function without the other. What options do i have, from looking we can setup Sub Domain, cluster the servers, etc. What are the pro's and con's of each setup and what process is involved. Any articles or Techsupport's welcome.
