Script Download: SyncNPSConfiguration.ziphttp://gallery.technet.microsoft.com/scriptcenter/Synchronizes-configurations-983962bf
In some scenarios, you may deploy multiple RADIUS servers instead of one central RADIUS server and other servers that act as proxy servers. However, it is difficult to ensure the consistency of the configurations of multiple RADIUS proxy servers. IT Administrators have to use the "netsh nps export" command to export a configuration file, and then use the "netsh nps import" command to import it to other NPS servers manually. There is no automatic way to synchronize the servers.
