Thread: Can't connect to wireless (certificate issue)

I have a laptop running Vista here as well as when I try to hook up to our wireless I get a message saying:

"A certificate cannot be found that can be used with this Extensible Authentication Protocol."

Previous to this I was getting that the certificate was expired. I did a look for to locate any expired certificates as well as deleted them hoping that they would reload. I tried physically loading it from our certificate server but I could have done it incorrect. I am a pretty new admin as well as have never worked with certificates before. Any ideas or impending would be much respected.

Based on my research, I would suggest the subsequent:

1. Concerning the error message, I suspect the certificate is missing or expired, we might require enrolling a latest valid one. Therefore, we require making sure what the certificate for, PC or user. If the certificate is for the PC, we may need a new PC certificate; similarly, if it is for user, we require a user certificate.

2. Please confirm if you have configured Certificate Autoenrollment policy.

For Certificate Autoenrollment, please also refer to:

Checklist: Configuring certificate autoenrollment

3. Meanwhile, I would like to share the subsequent document with you:

May I know your detail steps of enrolling the certificate? The more comprehensive, the better. After getting this, we will carry out some additional researches as well as check if the steps are proper.

Thanks.
