Event ID 4002 — WLAN AutoConfig Service

Applies To: Windows Server 2008

WLAN AutoConfig is a service that configures wireless security and connectivity settings. WLAN AutoConfig configures Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless adapters for connectivity to ad-hoc wireless networks, small-office wireless infrastructure networks, and for networks that provide 802.1X-authenticated network access. When enabled, WLAN AutoConfig settings apply to all IEEE 802.11 wireless network adapters that are installed on a computer.
