Help needed with an expired RAS and IAS Server Certificate

Recently my users started to experience problems getting onto our internal wireless network. As I am fairly new, I do not know how it is configured but through the event viewer I saw this - "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."

I have opened Certificate Services on the server (my NPS) and noticed that the certificate expired on 17th December.  I figured out how to create a new personal certificate but I am stuck as to what to do now.  Do I drag it into the Trusted Root Certificate Authority?  How do I deploy it?  I have found where I can do this in Group Policy but I cannot see how it was done before, that is to say that in Group Policy, the original certificate is not there.  How do I test this new certificate works and am I supposed to assign a key to it or something?

Any help would be gratefully received.

Many thanks for your help, I looked where you instructed me to and found where the certificate was configured but it gave a different date to the expired one and one that showed an expiry of 11th July this year.  I looked for the new one I created and though I think I found it (there were only four to choose from) this too gave me a completely different date.  The new one I created showed an expiry of twelve months time, this one gave me an expiry of 2019 - so I am left rather baffled.  Either way, changing the certificate did not resolve the issue so my boss took control and reconfigured our WAPs to use a pre-shared key, thus bypassing RADIUS/NPS.  To be honest, where we are located, this will suffice I think, so I would say this question is now redundant.

Thanks very much for your comprehensive assistance.
