2.) Disabling Microsoft Windows 802.1X compliant software

Since Microsoft Windows ships with its own 802.1X compliant client software, the Client service needs to disable it before starting the WPA supplicant. The Microsoft 802.1X compliant client software consists of:

Table 14–5Microsoft 802.1X compliant client software

Service Friendly Name	Service Name
Wired AutoConfig	•	WZO (prior to Windows Vista)
	•	dot3svc (Windows Vista)
WLAN AutoConfig	Wlansvc
ndisuio	User Mode Input Output Driver

Once those services have been stopped by the client, the client will start the driver service that is necessary for handling requests from the switch.

After all supplicants have been terminated, they will be (re-) enabled. To verify for a successful disabling process, verbose output is available:

3.) Starting the wpa-supplicant

The " Client" service will start a WPA supplicant, named "wpa_supplicant.exe", for all supported network interfaces given following circumstances:

•"1.1.A is set to enabled

•"1.1.B is set to enabled for the network interface to use 802.1X is set to enabled
