Nothing to confiugre : it should not ask anything ;)

What is your current configuration :
How many servers, their names and IPs, the CAS Array name, are other roles on the servers, are they under the same AD site (they should), and so on.
AkhaterConnect With a Mentor Commented:
CAS arrays are created when you have more than one CAS server in the same AD site they are created using the following

New-ClientAccessArray -FQDN -Name ""

You also need to add in your local DNS an A record for pointing to the NLB ip of your CAS servers

Do we need to configure NLB? How can we configure NLB for CAS.
AkhaterConnect With a Mentor Commented:
yes you need to do NLB for the CAS servers or else how can I share the same IP?

for NLB this is a video who will walk you through how to get start with it just follow the NLB part of it

Keep it unicast not multicast

also note you need 2 NIC on each CAS so the CAS servers should have a private network between each others for heartbeat

here is another tutorial covering it in details

Be carefull: Don't set any NLB if your CAS roles are on the same server than the Mailbox role. That's not supported.

that's also an article to the cas array configuration :
