Switching from WDS to MDT

imagingmdtpxe-bootwdswindows

I am in the process of moving from WDS to MDT. I will be installing MDT alongside WDS on the same box. The concept I am not grasping is at what point in this process will clients pxe boot to the MDT service instead of the already established WDS instance?

Thanks in advance!

MDT uses WDS for pre-boot. Within MDT, you will generate a boot image. Within WDS, you will import this boot image and make it available to PXE clients to choose during PXE Boot.

From MDT Workbench:

  • Configure all the properties of your environment by right-clicking the MDT Deployment share, and selecting properties.
  • Most of the boot image settings are under the 'Windows PE' tab and the 'Bootstrap.ini'
  • When your settings are ready, or anytime you need to refresh your boot images, right-click the MDT Deployment share and select 'Update Deployment Share.'
  • New boot images are generated in your deployment share location under <DeploymentSharePath>\Boot. They are named LiteTouchPE_<bitness>.wim.

On the WDS console:

  • Right-Click 'Boot Images' and 'Add boot image.'
  • Navigate to the where the boot image is saved and select it.
  • Provide a name and description.
  • Complete adding the image to WDS.

In the future, you can update the existing boot image in WDS, when a new one is generated in MDT.

Change the properties of the WDS server and choose default boot images if you want one image to boot by default, over another, or change how PXE devices are presented boot images, and selections.

When clients boot the LiteTouch image, the MDT deployment will begin however you have it configured.

You'll need to generate a new boot image whenever you update your bootstrap.ini or Windows PE properties, or if you upgrade MDT or your Windows ADK environment. You do not need to update the boot image, if all you do is change other MDT features like the Task Sequence or Drivers (unless, ofcourse, you are changing drivers in the Windows PE environment). You are basically deploying a pre-configured WinPE environment, with necessary drivers, and settings that tells the client where to connect to get further instructions from MDT.
