I'm trying to architect an NPS solution that has no single point of failure. Based on the reading i've done thus far it seems NPS back end with NPS proxy servers (at least two) in front is the way to go. I would like to be able to provide one single FQDN or IP address for access to NPS services but not via DNS round-robin.
It seems the optimal solution would be to use a third-party HW load balancing solution in front of the NPS back-end servers directly but my research seems to indicate this won't work. In lieu of that, what about HW load balancing to the proxy servers first and then configuring the proxies as per the TechNet article? Has anyone done this successfully?
