We went WNLB for a couple of reasons- $ and it was supported "happily" for our size/needs. Pretty sure it still is but MS doesn't seem to like it nearly as much as they used to-I'd guess based on real world experience? Today, those size/needs would steer towards HLB. IIRC it was a pain for us to set up and get going properly- whether that was WNLB, me, or just all the #$^! that was going on at the time, I dunno. Once it was going I guess it LB's well enough as long as all the boxes were up. not that it was a regular occurrence by any means but if we lost/had to reboot a box it did screw with all the connections on that box. Had to fiddle with patching too (drainstopping etc) but so it goes. Also unless we missed something obvious, the only health checking you have is basically a ping test, HLB goes past that.

This one I'll rate at a full .02 PC- Given you're going there anyway, get the network guys to make their decision and skip WNLB altogether:) Paul ________________________________ From: sms adm [sms...@gmail.com] Sent: Friday, June 17, 2011 4:35 PM To: MS-Exchange Admin Issues Subject: Re: Exchange 2010 design How reliable was your WNLB? We're planning to do the same ... start with WNLB and move to HW NLB when our network guys decide what they will buy and when.

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). 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!
