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.
For detailed information about a Windows-based authentication infrastructure, see Wireless Deployment Technology and Component Overview.
For detailed information about how to deploy a wireless LAN using IEEE 802.1X authentication, see Deployment of Protected 802.11 Networks Using Microsoft Windows.
For information about how to troubleshoot wireless connectivity on wireless networks that do not use 802.1X authentication, see Troubleshooting Microsoft Windows XP-based Wireless Networks in the Small Office or Home Office.
Troubleshooting Tools in Windows Wireless AP Troubleshooting Tools IAS Troubleshooting Tools Troubleshooting IAS Authentication and Authorization Summary Related Links The tools for troubleshooting wireless connections in Windows XP and Windows Server 2003 are the Network Connections folder and tracing.
The Network Connections folder and the notification area icons provide information about the state of the authentication.
If an authentication requires additional information from the user, such as selecting one of multiple user certificates, a text balloon appears instructing the user.Within the Network Connections folder, the text under the name of the connection corresponding to the wireless network adapter indicates the status of the connection.Figure 1 shows the information available for a wireless connection in the Windows XP Network Connections folder.In Windows XP Service Pack 2 (SP2) and Windows Server 2003 with Service Pack 1, the Repair capability has been enhanced for wireless connections.You can access the Repair capability through the Repair context menu option of a connection or from the Repair button on the Support tab of the Status dialog box of a connection.When you repair a wireless connection, it is disabled and re-enabled, which clears many error conditions on wireless network adapters.
