Hyper-V Server 2008 R2 with two VM (how to setup NLB)

Hi

I have Hyper-V server 2008 R2, two virtual servers (2008 R2 standard
core) and one management station Win 7 for testing purposes.

I am trying to setup NLB between two virtual servers.

In virtual network manager I've setup two internal networks and asign
them both to each virtual server.

In both virtual servers installed NLB and checked binding order with
wmic nicconfig so that virtual internal nic public is first and for NLB
is second in order.

Also I put in registry value of 1 for IPEnableRouter in TCP IP
Parameters in registry.

When I run NLB Manager at Win 7 to create NLB Cluster I am entering IP
of public nic on node1 and choose NLB NIC to create cluster.

After all is done I get info that Begin Configuration change and after
that two errors:

The interface is misconfigured

Cluster IP address (CLUSTERIP) not added to TCPIP properties
Dedicated IP address (NODE1NLBIP) not added to TCPIP properties

The bind operation was successful but NLB is not responding to queries.

Processing update 2 from "NLB Manager on Win7"
Starting update...
Going to bind NLB...
Bind operation succeeded.
Error reading cluster configuration
Update failed with status code 0x8004100a.

When I check at virtual server node 1 cmd I seed that now I have only
public interface. After restarting virtual server there are two nic,
public and NLB but NLB cluster does not work.

In article < >,
says...

=> The interface is misconfigured
=> The bind operation was successful but NLB is not responding to
queries.

Here is solution (did not tested yet).

It seems that NLB interfaces must have MAC spoofing enabled.
