I have deployed on two sites Zen Load Balancer. http://www.zenloadbalancer.org/ - they have been in place about three months with no problems reported. It is open source, and took me less than an hour to implement. I put them in to VMWARE so the biggest headache was getting the VMWARE tools installed as I am not a Linux person by any means. As with many open source projects, you can get commercial support if you wish. It isn't as feature rich as Kemp's etc, but it is doing the job for those two sites where I had no budget to work with and didn't want to use WNLB. Blog posting on that is being written at the moment.
If you want something more substantial, then I will echo the other posts and look at the Kemp. I have their virtual load balancers deployed in a number of locations and they just sit there and do the job.

From: Tom Miller [mailto:tmil...@sfgtrust.com] Sent: Friday, January 11, 2013 3:50 PM To: NT System Admin Issues Subject: Looking for affordable load balancing solution We currently use Windows Network Load Balancing for our Exchange 2010 environment. It's okay, but not great. There was a hiccup yesterday in NLB and it caused our system to disconnect all users at once. Looking to avoid this in the future, anyone have any suggestions for alternatives? Appliance or software solution - either is fine. I've used Citrix Netscalers in the past for XenApp, but I know they can also do load balancing.
