exchange 2010 cas nlb nic and dynamic mac spoofing

Hi Experts,

I am preparing my exchange network environment and one of the requirement for the NICs we use for the NLB network mush support dynamic MAC spoofing, i am wondering what a dynamic MAC spoofing is and how do i know if my server's NICs support this? The NLB we use is MS NLB and the OS is windows 2008 R2

The NICs on the server are:-
Broadcom NetXtreme II Gigabit Ethernet (2 ports, on board)
Intel Gigabit ET Quad Port Server Adapter

thanks.

I have been told that there was an issue with the Intel Gigabit ET Quad Port Server Adapter when our colleague tried to enable dynamic mac spoofing on one of the NIC in this card and this is the reason i asked this question.

we will run the NLB in unicast mode and thus we need this feature.

I checked the manual of the Broadcom card and I cannot find any word about dynamic mac spoofing.

However, I found the 'Locally Administered Address' in the device manage's broadcom card advanced properties, is that this is the one i need?

From the manual:
Locally Administered Address. The Locally Administered Address is a user-defined MAC address that is used in place of the MAC address originally assigned to the network adapter.

As I found similar setting in Intel NICs (Locally Administered Address) and because of the previous report that there was a problem with the Intel Gigabit ET Quad Port Server Adapter, I am not sure if the Locally Administered Address is what I need.

thanks!
