PC start-up process keep delay time

[Da ICS16]

Dear Cisco,

We user ISE v 3.1 P10 with Closed-Mode configuration.

We notice when pc start up un till log in AD user successful to delay more time. Some times it take round over 5mins or more than.

Kindly share your commend / good practice to reduce the slow log in time.

Best Regards.

@Da ICS16 are the computers configured for "user or computer authentication" or "user authentication" or just "computer authentication". What do the ISE live logs indicate for the computer? From the CLI of the switch run "show authentication session interface x/y/z detail" whilst the computer is starting up and whilst there is the delay. Provide the output for review.
