Hi Airhead,

We'll need to understand a bit more information about your deployment but if I take a guess I suspect this is the certificate used for machine authentication. The mobile devices I suspect aren't doing machine authentication so there for not having issues. 

 

If you take a look at the certificate, show is the Trusted CA? They will need to generate a new certificate for you if the existing one has expired. 

 

If you are using the Aruba certificate then follow the below:

That is because all of those other operating systems will allow you to operate with an expired certificate.  Windows is a system used in the enterprise and it has protection to ensure that you are not compromised because of an expired certificate.  

 

If someone puts up an SSID that looks exactly like yours with an expired certificate, they could easily allow your users to connect to the fake SSID and collect all of their usernames and passwords.

 

When your Radius Server was built, a user generated a server certificate.  You need to generate another certificate that is trusted by your Windows Devices.
