I need to know the client OS 

And the ISE cert. Is ot wildcard or not and are you use multi PSN and add it IP or hostname as SAN in cert.

The os is Windows and when this happens authentication is done with the computer name. authentication with user account is ok.

randomly happens not all client have this issue.

ISE cert. Is not wildcard and i use multi PSN and add hostname as SAN in cert.

For anyone who has problem, the windows 10 credential guard is causing the problem.
