No. The ONLY role supported in a failover-cluster in Exchange 2007 is mailbox.
HT load-balancing is done automatically. CAS load-balancing is handled by NLBS. You can consider CAS+HT to be FE (more or less) and MB to be BE (more or less). Clients authenticate via the CAS. CAS should not be in DMZ. You either publish it with ISA (or similar), or punch 443 through the firewall. Regards, Michael B.

How about this scenario: 2 servers in a failover cluster running a single VM with Hub Transport and Mailboxes on private LAN. 2 servers in a failover cluster running a single VM with CAS in a DMZ. I think I am getting muddled translating FE/BE to the new E2K7 roles. Where will clients go to authenticate? The DMZ?

What is the goal? Four servers gives you completely redundant, with clustering. (CAS/HT times 2, MB times 2) You can get completely redundant with manual failover with two (CAS/HT/MB with LCR).

I just can't stand the idea of six servers for 500 users. Seems a bit too many. Setup a failover cluster with Exchange 2007 running in a hyper-v VM. This way all of the roles can run on a single (heck even multiple) VM and failover as needed. Thoughts? things I should be worried about? You know, besides Hyper-v not even being released yet :) Jason Tierney, MCITP Vice President, Consulting Services Corporate Network Services "Count on Us" direct: 240-425-4441 -----Original Message----- From: Michael B.
