ok ended getting rid of error manually going through group policy objects , removing accounts showed sid instead of account name, ie not resolving valid account.  once removed policies, did gpupdate again, errors gone event log.

now radius authentication issue, these items fixing original problem, tested again , still getting result:

radius client authentication failed (mschap error: e=691 r=0 v=3)
