A workstation was joined to the domain. It was ypgraded from Win 7 to Win 10 and now ClearPass gives me this error:
EAP-PEAP: fatal alert by client - unknown_ca
eap-tls: Error in establishing TLS session
802.1x is configured on the switchport.
I'm thinking something changed because of the upgrade and now ClearPass won't authenticate because it thinks it's a different workstation?
I removed aaa config off port, bounced it, then reapplied aaa config.
ClearPass still won't authenticate it?
Any suggestions?
