NPS Radius

[leyakhath muhammed]

How can I ensure high availability for RADIUS service in Windows Server environment ? so it can withstand loss or even temporary downtime of any particular server holding NPS role.

Please advice me 

Thanks

As with any HA, it needs to be implemented redundantly. Sadly, NPS makes this a little bit hard to maintain as there is no synchronization of changed policies. Whenever your network has grown to a size where you need a redundant NPS, I would consider to move to Cisco ISE.

Hello @leyakhath muhammed 

NPS proxy server load balancing. General idea: use NPS configured as a RADIUS proxy to load balance connection requests between multiple NPSs or other RADIUS servers.
