Changes to the 802.1X-based wired network connection settings in Windows XP Service Pack 3
This article discusses the changes that have been made to the 802.1X-based wired network connection settings in Windows XP Service Pack 3 (SP3). This article also includes information about how Windows XP SP3 stores the wired network connection profile information.
In versions of Windows XP that are earlier than Windows XP Service Pack 3 (SP3), the built-in 802.1X-based wired network connection uses the AuthMode and SupplicantMode registry entries to determine the following:
- The type of authentication that must be used.
- How the computer must behave upon authentication.
The default value for the supplicant mode in Windows XP SP3 for a client that uses a wired network connection is 3. In this setting value, the client sends an Extensible Authentication Protocol over LAN (EAPOL)-Start message for each change in user context.
The default value for the authentication mode in Windows XP SP3 for a client that uses a wired network connection is 1. In this setting value, the client uses a combination of computer and user credentials for authentication. To enable computer-only authentication, you must add the appropriate settings to the XML file for the wired network connection profile.
