Building NLB Exchange 2010 RTM CAS / HT Servers (Hyper-V) – Part 3
NOTE: Before configuring anything after the deployment of the CAS server roles, remember that if any send or receive connectors are configured, these would supersede the configured Exchange 2003 connectors or they would take precedence over the default SMTP virtual server in Exchange 2003 if no connectors are configured at all. My recommendation would be to install the mailbox server roles and create mail databases before performing any CAS configuration tasks.
The following steps should be performed to specify the CAS Array. All this does is specify the connection point to the client. The virtual IP address of the NLB servers will be used as a connection point for MAPI clients.
The CAS Array can be set by opening the Exchange Management Shell and typing the following command:
New-ClientAccessArray –Name “MAPI Client Connection Point” –Fqdn “Outlook.Morecoffeeany1.com” –Site “Default-First-Site-Name” Read more »

Before using the NLB cluster for Exchange, the NICs should be able to forward requests between each other. This is achieved by running the following command on the cluster NICs on each node of the cluster:
netsh interface ipv4 set int “Cluster Only LAN” forwarding=enabled
The reason for this configuration is as clear as mud at this stage. However, I assume that it has to do with the fact that the cluster only interface does not have a gateway configured for the connection. This connection functions on a broadcast anyway. According to the Microsoft Enterprise Networking Team, the packet will be dropped since IP forwarding is not enabled by default in Windows 2008 and the inbound packet comes in without a subnet mask.
Now we’re ready to install Exchange 2010. First I’ll run the ExPDA to check the environment for the Exchange 2010 prerequisites. If you’re not sure how download and use the ExPDA, check my earlier blog post on how to do this.
