Good news ! I did some tests. My issue is completely solved. The very good article sent by @MRCUR did help. https://documentation.meraki.com/MS/Access_Control/Configuring_802.1X_Wired_Authentication_on_a_Windows_7_Client Some improvements could be added to the article : The good old XP (SP3) does work with what is explained for WIN7. The tab "authentication" will not appear, if the service "Wired autoconfig" is not correctly working. Not domain-joined workstations can authenticate with RADIUS. Just need to uncheck "Automatically use my Windows logon name and password (and domain if any)". PEAP could not work if "Validate server certificate" is checked and Certification Authority is not reachable by workstation. For PEAP, the NPS server needs to have a certificate ; that certificate should be validated by the workstation (such as browser does for HTTPS). Many thanks to community ! I will probably be back for BYOD, Bootstrap Profile, and other interesting subjects.
