sorry, couldn't remember the list address for win2k bits....besides, you lot
will probably know the answer
, well you better had or else I will stamp my feet and cry until you do..ok

anyway..a question on network load balancing in a switched environment

I want to build two load balanced IIS servers on win2k advanced server.  

I am trying to understand how NLB works in its two modes Unicast and
Multicast.

In Uni-cast I think that the cluster host responds with a unique source mac
address and in multi-cast
the cluster host responds with a multicast address...

My confusion is this :

In Unicast mode, if the switch sees the source MAC address and then
remembers this as the MAC address
for that port, presumably all subsequent frames for that MAC address will go
out of that specific port only??
in this case, how would all cluster hosts receive the frames??
