Server 2012 R2 Dot1x errors RRS feed

  • Question

  • Hi there, 

    I've configured NPS to authenticate workstations based on their machine certificates when plugged in to a Cisco switch. Radius is set up on the switch and the policies are set up on the server. It's been working in a test environment but when implementing the solution on our production environment the workstations report an 'Explicit EAP failure' with an error code of 0x8009030c.

    I've tried several combinations of policies within NPS or within the authentication tab on the workstation and can't get it to work. Any help would be much appreciated. 

    Many thanks.
