Your network contains an Active Directory domain.

To deploy the Windows 11 image to 100 devices by using MDT, you should perform the following three actions in sequence:

Install Windows Deployment Services (WDS) on the server. WDS is a role that enables you to deploy Windows operating systems over the network by using PXE boot and multicast technologies. You need to install WDS before you can enable multicast and configure the boot images for MDT. You can install WDS by using the Server Manager or PowerShell1.

Create a deployment share on the server. A deployment share is a folder that contains the MDT files, scripts, applications, drivers, operating systems, and task sequences that you use to deploy Windows. You need to create a deployment share by using the MDT Deployment Workbench2.

Add the Windows 11 image and create a task sequence in the deployment share. An image is a file that contains a snapshot of a Windows installation. A task sequence is a set of steps that MDT executes to install Windows and configure the settings. You need to add the Windows 11 image by importing it from a source folder or a WIM file, and create a task sequence by using a template or customizing your own3.

These are the basic steps to prepare for deploying Windows 11 with MDT. For more details and guidance, you can refer to the web search results I found for you by using search_web("deploy Windows 11 image with MDT").
