Hi Philip,   Thanks for the hint. Are there any other possible reasons for this? Still struggle the reason resulting the looping of success then reauthenticate.    I used following method (similar, my server is WS2019) to manually add certificate to a Laptop, but the problem still the same. logon success, then restart again, "Reason: Onex Auth Timeout".    Obtaining a Machine Certificate via Web Enrollment from a Windows Server 2003 Enterprise CA (isaserver.org)   What I added: Server side, use IIS request a certificate for Web Server from CA_Root. Server side, from https://domain.local to assign an Administrator Certificate for Radius Server. on laptop:  install the Administrator Certification to Laptop, in mmc console, under "Certificates\Personal" on laptop: import the CA_Root to "Certificates\Trusted Root Certification Authorities" (mmc console)   Regards, nzou ...
