Igmp Multicast Nlb
up NLB in 2k8R2(in hyperv). 2 nodes, each has 2 NICS, Followed the instructions, which were written in 2007.After completing the Statusis misconfigured. I found one write-up that saidchange the nics mac from dynamic to static which I did, I removed and re-created the cluster. Nogo, still misconfigured.All NICS are on the same subnet, nothing says they need to be on differentsubnets, I guess I will try that though. anyadvice?~M Friday, April 23, 2010 11:33 PM All replies 0 Sign in to vote Hello, Thank you for your post here. Do you append synthetic adapter on the VMs? If yes, please check how it works if you replace it with legacy adapter. Windows Server 2008 Hyper-V virtual machines generate a Stop error when NLB is configured or when the NLB cluster does not converge as expected http://support.microsoft.com/kb/953828 If you have any questions or concerns, please do not hesitate to let me know.

NLB on one NIC of the Node. Physical connection of this NIC is very important. If you are using a Layer 3 switch you will need to plug the NIC into a hub then uplink the hub to the L3 switch. If you are using a Layer 2 switch you can plug the NIC directly into a port on the hub. There is a registry setting called MaskSourceMac that needs to correspond to the physical connection of the NLB NIC. If you are plugged directly into the L2 switch you will need to set MSM=1. If you are using a hub that is up linked to the switch set MSM=0 (see KB193602 below) If you want traffic to come into the NLB NIC then all subsequent traffic to go out of the second (non-NLB) NIC, set the binding order and metric of the NLB NIC to 2. As a result, you will need to set the binding order and metric for the second (non-NLB) NIC to 1. The Default Gateway, in a two NIC scenario, is a key setting. If you check IPCONFIG and you notice that the Default Gateway is set on both NICs and is a different IP address, this will cause problems. We recommend you pick one Default Gateway and set it on the second NIC (non-NLB) NIC, leaving the Default Gateway setting on the NLB NIC blank.
