Windows 2003 Enterprise Clustering - networking

I have two identical Dell PowerEdge 2650s.  Primary hard drive is about 36 GB.  There's a shared PowerVault with two RAID volumes (one for the quorum and one for shared storage).  I need to create a cluster running the following services DNS (Primary for the domain), Exchange 2003, and WINS.  Each system has two dual channel Network adapters (4 NICs in all).  I understand I need to configure two NICs for cluster private communictions and the other two for public communications.  I'm confused about IPs and subnets to be used.  Does each NIC get it's own subnet with a corresponding subnet on the second server (node2)?  For example, consider:

node 1                                                                      node 2
Private NIC 192.168.200.1/24                                      192.168.200.2/24
Private NIC 192.168.201.1/24                                      192.168.201.2/24
Public NIC 192.168.100.1/24                                        192.168.100.2/24
Public NIC 192.168.101.1/24                                        192.168.101.2/24

Is that the correct configuration.  If so, when I configure DNS, does it get configured with the public cluster IP or are there special considerations here?

Thanks,

~Mark

Read this about configuring hosts with nics on different network:

http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/clustering/nlbbp.mspx

Since the cluster has fixed addreses, you'll configure dns to respond only on request from the public addresses, and I think this is enough.

So, if I understand what this is telling me, I can use the above configuration and if my virtual public IP address 192.168.11.6, I just make sure all services respond to this IP address.  Correct?
