How to fix the Windows Security Alert that appears during wireless connection authentication? RRS feed

  • Question

  • Our users are currently getting  error "The server “<Authentication server>” presented a valid certificate issued by “<CA name>”, but “<CA name>” is not configured as a valid trust anchor for this profile." when connecting to the office wireless connection:-

    We use Microsoft NPS server as the Radius server.
    I have made sure the NPS server cert is not expired.
    NPS server is also the Enterprise CA server(thus both the "Radius Server" and "Root CA" fields have the name of the NPS server).
    The cert applied on the NPS authentication profile is the CA cert which allows all purposes. So the certification path has only 1 cert in the chain (CAs own cart).
    And this cert is in the trusted root Certification authorities list of the client computers.
    What can I do to resolve this problem.
