SYMPTOMS
You disable the Wireless Zero Configuration service by using the Wireless Zero Configuration API in Microsoft Windows CE 5.0. However, the Wireless Zero Configuration service may keep setting service set identifiers (SSIDs) that are not valid on the wireless network driver.

This problem occurs if an application sends an SSID to the wireless network driver after you disable the Wireless Zero Configuration service.

Note The SSIDs that are not valid are made up of 32 bytes of random characters.
