Abstract This article describes the tools used to troubleshoot a Microsoft Windows XP or Windows Server 2003-based wireless client, a wireless access point (AP), and the Internet Authentication Service (IAS) when using Institute of Electrical and Electronic Engineers (IEEE) 802.1X authentication for IEEE 802.11-based wireless connections.This article also describes the most common problems with IAS authentication and authorization, certificate properties, and the process of certificate validation for both wireless client and IAS server certificates.If the wireless adapter has an Automatic Private IP Addressing (APIPA) address (169.254.0.0/16) or the configured alternate IP address, then authentication has failed and the Windows-based wireless client is still associated with the wireless AP.If the authentication fails and the association is still in place, the wireless adapter is enabled and TCP/IP performs its normal configuration process.For detailed information about a Windows-based authentication infrastructure, see Wireless Deployment Technology and Component Overview.

To obtain detailed information about the EAP authentication process, try the authentication process again and view the and files in the \Tracing folder.

Verify that this string is correct from the properties of the Smart Card and Other Certificate EAP type on the Authentication tab from the properties of the wireless connection that corresponds to the wireless LAN network adapter.

Figure 3 shows the default properties of the Smart Card and Other Certificate EAP type for Windows XP with no service packs installed and Windows 2000.

To obtain detailed information about the Wireless Zero Configuration service for Windows XP SP2 or Windows Server 2003 with Service Pack 1 and the EAP authentication process for all versions of Windows XP or Windows Server 2003, you must enable tracing by typing netsh ras set tracing * enabled at a command prompt.
