IEEE 802.1X authentication protocol support for WinPE

Microsoft has released hotfixes that now add 802.1x support to both WinPE 2.1 and WinPE 3.0. Here are the links to the hotfixes.

WinPE 2.1: http://support.microsoft.com/kb/975483

WinPE 3.0 (Windows 7 & Server 2008 R2): http://support.microsoft.com/kb/972831

Step by Step Instructions to Inject the update using DISM.

1) Once you have downloaded the update, extract the files to your deployment server. In this example, I created a folder on my E:\ called 802PE.

2) Mount the LiteTouchPE_x86.wim using DISM: DISM /Mount-WIM /WIMFile:E:\DeploymentShare$\Boot\LiteTouchPE_x86.WIM /index:1 /MountDir:E:\Mount


3) Inject the package: DISM /Image:E:\Mount /LogPath:AddPackage.log /Add-Package /PackagePath:E:\802PE\Windows6.1-KB972831-x86.cab

4) Unmount and Commit your changes: DISM /Unmount-WIM /Commit /MountDir:E:\Mount
5) As an additional step you can validate the package was installed successfully: DISM /Image:E:\Mount /Get-Packages (Note: When you add the package in step 3 it should tell you, “The operation completed successfully” if the package injected with no errors.)
