Hello, I have searched online for several hours and not yet been able to resolve this one. I have an Aruba wireless Controller that uses EAP authentication so my 120 client machines connect automatically to the wifi (as long as their PC is in the proper Active Directory group). On the NPS server in Certificates mmc i noticed the certificate expired yesterday. the past several years i have requested the new cert, pointed the Network Policies under Network Policy Server to the new cert, and the wifi functions fine. This year it will not work. I have confirmed NPS is pointed to the new cert but no avail. Error i get on the client machine in event viewer after attempting to connect is 36881 - "The certificate received from the remote server has either expired or is not yet valid. The SSL connection request has failed. The attached data contains the server certificate." Any ideas on what i should be looking at?
