Running 6.1.2 on a 3400, the first NPS server in the domain authenticates correctly, but the backup NPS has an issue with the request (Event ID 18). Could this be a certificate error? Our switches and applications authenticate OK on the 2nd NPS. I didn't configure our 3400 for the first NPS, so I'm not sure what I may be missing.

#1 reason - Makes sure the preshared key for Radius Clients is correct on the second NPS for that controller.

Confirm the 2nd NPS server has the proper radius client secret defined.

If you've verified the preshared key and it's still giving that error,
1.) Confirm that you have the controller listed as a RADIUS client on the second NPS server.
2.) Make sure the RADIUS policy is enabled for the EAP type you're using (e.g. PEAP).
3.) If you're using a server side certificate, make sure the correct one is selected for that policy.
Hope this helps!
