If a computer that is running Windows Vista or Windows Server 2008 uses a wireless network connection, you cannot use the EAP method to authenticate the computer

This article has been archived. It is offered "as is" and will no longer be updated.
Symptoms
Consider the following scenario. You try to use the Extensible Authentication Protocol (EAP) method to authenticate a client computer that is running Windows Vista or Windows Server 2008 by using a wireless network connection. In this scenario, the EAP authentication fails.
Cause
This problem occurs because, in Windows Vista or in Windows Server 2008, the EAP support for wireless network connections discards the EAP Notification Request message without a response. Therefore, the EAP authenticator cannot continue without receiving a response message.
