CAS Array configuration
If the network was configured in teaming, you have to break the teaming
before configuring the CAS array.
- On both network cards on both servers definitions:
check mark ipv6 even
if we don't need it.
- On the NLB network card definitions on both servers:
on the ipv4 properties
remove default gateway definition.
DNS configuration
Open the DNS in the root Domain and create a new Host with the name where the clients will connect.
Give the IP address and check the "Create associated pointer (PTR) record"
Open the first HUB/CAS server
Open the Exchange powershell
[PS] C:\Windows\system32>Import-Module servermanager
[PS] C:\Windows\system32>Add-WindowsFeature nlb
You should receive the result below
Open the second Hub/CAS server and run exaclty the same functions
[PS] C:\Windows\system32>Import-Module servermanager
[PS] C:\Windows\system32>Add-WindowsFeature nlb
Go back to the first node and run on the Exchange powershell
[PS] C:\Windows\system32>Import-Module NetworkLoadBalancingClusters
Note: Make sure you have an interface for the NLB configuration and the same
network name for both servers
[PS] C:\Windows\system32>New-NlbCluster -InterfaceName NLB -ClusterName casarray
-HostName HubCas01 -ClusterPrimaryIP 192.168.0.1 -OperationMode MultiCast
Result:

Then run the following
[PS] C:\Windows\system32>Get-NlbClusterPortRule
|Remove-NlbClusterPortRule -Force
[PS] C:\Windows\system32>Get-NlbCluster | Add-NlbClusterPortRule

[PS] C:\Windows\system32>Get-NlbCluster | Add-NlbClusterPortRule

Adding the second node to the cluster (from the first node)

Creating the CAS array
[PS] C:\Windows\system32>New-ClientAccessArray -Name "CAS
Array" -fqdn Exmail.domain.com –site Sydney
You should receive the result below
Name Site Fqdn Members
---- ---- ---- -------
CAS Array Sydney Exmail.domain.com {HubCas01, HubCas02}
In order to allow other vlans to access the cas enter the netsh command in
both Hub/CAS server:
C:\>netsh interface ipv4 set int "nlb" forwarding=enabled
