How to configure wired 802.1X for Windows Vista

   This guide requires a genuine version of Windows Vista. The guide was created on a computer running Windows Vista Enterprise, but should work on all editions. Since both Vista and this guide is relatively new, we urge you to
   contact studentby-drift (at) if you find any errors in this document or experience any problems using this guide.

   Before you start, you need to enable a service called Wired AutoConfig. Without this service enabled, you will not be able to authenticate, and thus not gain access to the network. To enable Wired AutoConfig:
    1. Click the Start button. In the Search box ("Start Search") type services.msc and press "Enter". You must be logged in as an administrator to start this service.
    2. In the Services dialog box, click the "Standard" tab (located in the lower part of the window).
    3. Scroll down to find the Wired AutoConfig service, right click and select "Start".
    4. If you want Wired AutoConfig to start automatically every time you start your computer, right click "Wired AutoConfig" again and select "Properties". In the General tab, set Startup type to Automatic. Click "OK" and then
       close the Services window.

   NB! If you are unable to log in after following this guide, try to right click on the taskbar (for example to the side of the clock in the lower right corner), uncheck "Hide inactive icons" and make sure that "show network
   connection" is checked. This will prevent Vista from authenticating with the hostname of your computer, rather than prompting you for your user name and password.

   You can now continue with the rest of the configuration:

  Click on the start button and select Control Panel.



 To be able to view all the elements in the control panel, you should select Classic View in the upper left corner.
   Next, double click Network and Sharing Center.


Here you can see that the network connection has not been established. Therefore,
   click Manage network connections on the left hand side of the window.



   Right click Local Area Connection and select Properties from the drop-down menu.



   Make sure that your network interface card is working properly. If the box in front
   of the arrow is empty, you need to install the drivers for your network interface card first.
   Next, click once with your left mouse button on Internet Protocol Version 4 (TCP/IPv4)
   and then click Properties.


   Make sure that your settings equals the ones in the above picture, and then click Advanced.


   Check that your settings equals the ones in the above picture. If not, remove all unnecessary elements.
   Next, click the DNS tab.


Make sure that your settings equals the ones in the above picture, and remove unnecessary elements, if any.


   Back in the Local Area Connection Properties window, click the Authentication tab.
   Check the Enable IEEE 802.1X authentication box and select Protected EAP (PEAP) in the drop-down menu.
   Next, click Settings.

   Make sure that Validate server certificate is unchecked. In the drop-down menu, select
   Secured password (EAP-MSCHAP v2). Click Configure.

   Uncheck Automatically use my Windows logon name and password (and domain if any).

   Next, click OK in this window and in the previous window (Protected EAP Properties). Click Close in
   the Local Area Connection Properties window. After a few seconds, a bubble looking something like this
   will appear in the lower right corner of the screen:


   Click the left mouse button inside the bubble. A window will appear, looking something like this:


   Enter your user name and password. Do not enter any logon domain. Click OK, and after a few seconds you should be online!
