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.
