Installing Second exchange 2013server

Hello all,

So I am going to be installing a second 2013 Exchange server in a secondary site that will have both Mail and CAS roles, same as the first. I plan to create a DAG between these two sites and have it so that if one server goes down the other can pick up the mail and deliver. Is there a walkthrough or a high level overview on how to get this accomplished. I know I will need to do the following:

1. Install exg2013
2. Create DAG and witness server.
3. Have MX record point to new server (is there any firewall rules I need to put in place? any tech net article?)
4. Have our ISP DNS servers point "" point to both servers.

I know I am probably missing a ton, but this is a work in progress and I am gathering my information before I begin.

That isn't going to work.
You need to ensure that you have AD sites and services configured correctly with the two locations in their own AD site. You will then need to have a unique host name ( "" perhaps?) pointing to the second server. Include it in your SSL certificate etc.

Otherwise both servers need to be identical in storage and network configuration, other than what they need to be unique (name and IP addresses). You should ensure the same security software is configured etc.
