Thanks for the replies, they set me off on a lot of reading. Unfortunatly I've been told that a hardware load balancer is out of the question at the moment, but I did find this link for a highly available 500 mailbox design (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=e0e93251-fc04-4 a18-8aa0-23817b6d0c97 <http://www.microsoft.com/downloads/en/details.aspx?FamilyID=e0e93251-fc04-4 a18-8aa0-23817b6d0c97> ) in my list archive, for an MS white paper which seems to describe an implementation that would fit with what I've been required to do. My only question would be, how "real world" are these white papers, if I followed a similar route would I end up with a practical solution? Thanks again,

I'm trying to plan new hardware to deploy Exchange 2010 (100 users, average mailbox size 500MB) and am looking at using two servers with CAS, HT and Mailbox roles installed on both and using DAG for high availability. I was thinking of using Windows NLB for load balancing,but have read that this can't be used with DAG (http://technet.microsoft.com/en-us/library/dd979781.aspx <http://technet.microsoft.com/en-us/library/dd979781.aspx> ). My question is, if I set up two additional servers with NLB installed and moved the CAS and HT roles to them, would this solution then provide the load balancing I'm looking for? Alternatively, would I be better off with two highly redundant servers and use one for Mailbox and one for CAS and HT? Thanks for any advice!
