Hi
I have a couple of wireless access points (AP's) that are unable to use our RADIUS server to authenticate.
This started happening after a power outage, and I did a gracefull shutdown of the RADIUS server. When the server was booted up the AP's appear to have lost the ability to authenticate users of both PC's and mobile devices.
I looked through the Network Policy server MMC and didn't find anything there.
Next I looked at the certificates and found 2 in the Personal>Certificates folder, that I think are related to this configuration. The odd thing is they expired the exact same day as the power outage.
So I tried to Renew and then Recreate the certificate's key. That's when I received the RPC server unavailable. I also tried creating a new key from scratch, same problem.
I did a lot of searching on the web so I have seen this thread and I have checked all the things recommended, none of the suggestions helped:

I must admit I am at a loss as to where to look next.
Help is very much appreciated.
