NLB for Windows Server on VirtualBox

Figuring out the network configuration took longer than I would have liked. Here is the handholding guide.

Steps Enable NLB on Two Nodes In VirtualBox

0. Create a Host-Only Network Adapter.
	a. The adapter doesn't need to provide dhcp.

1. Create 2 Windows Server 2008 R2 VirtualBox Machines.
	a. As you will more than likely need to patch and update the machine set the newtork for both to be
	the bridged adapter. This allows internet access.
	b. Add the IIS Role
	c. Add the NLB Feature.

2. On each VM set the network setting to be the Host-Only adapter made in step 0.
	a. Enable promiscuous mode for 'vm-only'

3. On each VM assign a static IPV4 address. ( Node1: 10.0.2.10, Node2: 10.0.2.11)

4. Ensure each node is able to ping the other.

5. On a Node 1 start the Network Load Balancing Manage : cmd -> nlbmgr.exe

6. Initial Cluster Setup (NlbMgr)
	a. When selecting the first node to add use the IP address of Node1.
	b. For the cluster address select 10.0.2.12
	c. Select multi-cast mode
	d. Port rules are specific to your use case but the defaults will probably work.

7. Cluster Setup for Node 2
	a. In NlbMgr select 'Add Host To Cluster'
	b. Use the IPAddress of Node2.


At this point you should have Cluster with Cluster Address 10.0.2.12 that is composed of two Nodes. Both Nodes should be converged.

If you have connectivity issues you might need to enable ICMPV4 in the firewall.
