I am building a network architecture from scratch for a small company (~20 users). I plan to use the "classical" model: -A server that contains Active Directory -A server that contains Exchange server
1 - Can we use Microsoft exchange without Microsoft active directory (ie not have a AD server at all)? 2- In order to have a fail-safe architecture, do we need 2 Domain controllers and 2 exhange servers (ie 4 in total)? or do we only need 2 domain controllers and 1 exchange server?
PS. Sorry guys for being lazy. I will hire a consultant certainly but at least I have an idea now about what to do. Thank you.
