INTRODUCTION

This article discusses how to enable computer-only authentication for an 802.1X-based network in Windows Vista, in Windows Server 2008, and in Windows XP Service Pack 3 (SP3).

MORE INFORMATION

Note The netsh wlan command that is described in this article exists only in Windows Vista and in Windows Server 2008. The netsh lan command exists only in Windows Vista, in Windows Server 2008, and in Windows XP Service Pack 3. These commands do not exist in any versions of Windows XP that are earlier than Windows XP Service Pack 3.

949984 Changes to the 802.1X-based wired network connection settings in Windows XP Service Pack 3
Windows Server 2003 and versions of Windows XP that are earlier than Windows XP SP3 store 802.1X computer and user authentication settings in the AuthMode registry entry in the following registry subkey:
HKEY_LOCAL_MACHINE\Software\Microsoft\EAPOL\Parameters\General\Global
However, the AuthMode registry entry is not valid in the following Windows operating systems:
  • Windows Vista
  • Windows Server 2008
  • Windows XP SP3 wired connections (However, the registry entry is valid for wireless connections.)
Note The AuthMode registry entry is valid for Windows XP SP3 wireless connections. However, the AuthMode registry entry is not valid for Windows XP SP3 wired 802.1X-based networks.

If computer-only authentication is configured in an environment that has Windows XP-based computers or Windows Server 2003-based computers, the settings are not applied to Windows Vista-based computers or to Windows Server 2008-based computers. To set the authentication mode for Windows Vista, for Windows Server 2008, or for Windows XP SP3 wired connections, you must modify the 802.1X network profile.

To enable computer-only authentication for an 802.X-based network in Windows Vista and in Windows Server 2008 for a wired network connection and for a wireless network connection, or in Windows XP SP3 for a wired network connection, follow these steps:
  1. Create a profile.

    Use one of the following procedures, depending on whether you are using a wired or a wireless network connection and as appropriate for your operating system.
    • Wired network connection (on Windows Vista or on Windows Server 2008)

      Create an 802.1X-based network profile on a wired network connection. To do this, follow these steps:
      1. Right-click the network connection icon in the notification area at the far right of the taskbar, and then click Network and Sharing Center.
      2. Under Tasks, click Manage Network Connections.
      3. Right-click the network connection that you want to configure, and then click Properties.

        If you are prompted for an administrator password or confirmation, type your password, or click Continue.
      4. Click the Authentication tab, specify the settings that you want, and then click OK.
    • Wired network connection (on Windows XP SP3)
      1. Before you create an 802.1X-based network profile in Windows XP SP3, the Wired AutoConfig service must be started and set to Automatic startup. To do this, follow these steps:
        1. Click Start, click Run, type services.msc, and then click OK.
        2. Locate the Wired AutoConfig service, right-click the service, and then click Properties.
        3. Change the startup type to Automatic, click Apply, then then click Start.
        4. Click OK to exit the Wired AutoConfig Properties dialog box.
      2. Create an 802.1X-based network profile on a wired network connection. To do this, follow these steps:
        1. Click Start, click Settings, and then click Network Connections.
        2. Right-click the network connection that you want to configure, and then click Properties.
        3. Click the Authentication tab, specify the settings that you want, and then click OK.
    • Wireless network connection (on Windows Vista and on Windows Server 2008)

      Create an 802.1X-based network profile on a wireless network connection. To do this, follow these steps:
      1. Right-click the network connection icon in the notification area at the far right of the taskbar, and then click Network and Sharing Center.
      2. Under Tasks, click Manage Wireless Networks.
      3. Click Add. The Wireless Network Wizard starts.
      4. Follow the instructions that are displayed on the screen to create a wireless network profile.
    • Wireless network connection (on Windows XP SP3)

      This step does not apply to Windows XP SP3 wireless network connections. Continue to set AuthMode for wireless XP SP3. See the "Authmode (on Windows XPSP3 Wireless connections)" section later in this article for more information.
  2. Export the network profile information to an XML file. To do this, follow these steps, as appropriate for the operating system that you are running.

    2. At the command prompt, type one of the following lines, depending on whether you are using a wired or a wireless network connection, and then press ENTER.
      • If you are using a wired network connection, type the following line:
        netsh lan export profile folder=c:\
      • If you are using a wireless network connection (This command is not valid for Windows XP SP3), type the following line:
        netsh wlan export profile folder=c:\
  3. Set the Authmode.

    Modify the network profile in the XML file to specify computer-only authentication, as appropriate for the operating system that you are running.

    Authmode (on Windows Vista, on Windows Server 2008, and on Windows XP SP3 (Wired connections))

    Note Windows XP SP3 and earlier versions of Windows XP do not support the netsh wlan command interface. For Windows XP SP3 wireless connections, continue to set AuthMode for wireless Windows XP SP3. See the "Authmode (on Windows XP SP3 (Wireless connections))" section later in this article.

    To do this, follow these steps:
    1. Start Notepad, and then open the XML file.
    2. In the XML file, locate the section that contains the OneX settings. The following is an example of this section:
      OneX xmlns="http://www.microsoft.com/networking/OneX/v1">
      
                                    <cacheUserData>false</cacheUserData>
      
                                    <authMode>machineOrUser</authMode>
      
                                     <EAPConfig>...</EAPConfig>
      
                      </OneX>
      
    3. Modify the <authMode> line as follows:
      <authMode>machine</authMode>
      The following is an example of the section that contains the OneX settings after it is modified:
      OneX xmlns="http://www.microsoft.com/networking/OneX/v1">
      
                                    <cacheUserData>false</cacheUserData>
      
                                    <authMode>machine</authMode>
      
                                     <EAPConfig>...</EAPConfig>
      
                      </OneX>
      
    4. Save, and then close the XML file.

      The authMode (OneX) element specifies the kind of credentials that are used for authentication. The following table describes the values that the authMode (OneX) element uses.
