I have setup Meraki wireless across multiple locations with an SSID for WPA-2 using a radius server on Windows Server 2012 R2 (virtual server in our data center). For some reason 2 of our sites fail when connecting and during testing via the Meraki dashboard. I have verified the IP addresses for the access points are included as RADIUS clients. I have looked through event viewer for errors, but I am not seeing any errors. I am not sure what to really look for. Based on the configuration I would think either all access points would fail or all would succeed. I have verified all are using the same DNS settings, firmware is up to date, and all Radius clients are using the same settings, including the same shared secret template. I have compared the main switch at various locations and nothing stands out. Our routers are managed by a third party, so I have not verified settings there, but everything should match. All sites are connected via MPLS. As of now I am getting around this issue by using another server, but it is a physical server scheduled to be decommissioned soon. As far as I can tell, settings are identical on both servers as far as NPS is concerned. I am sure I am just missing something, but not sure what else to look for. Any and all ideas would be appreciated. Thanks.
