MDT/WDS Multicast Fails after Update to Win 11 ADK/Winpe (22000.1)

I updated WADK and WINPE to windows 11 version (22000.1) on our MDT server
Updated deployment shares. Updated LitetouchPE.wim to support Multicast (WDS) following these instructions: https://learn.microsoft.com/en-us/mem/configmgr/mdt/known-issues
Updated WDS boot image with modified LiteTouchPE.wim
Updated: LiteTouchPE boot ISO (can confirm WDS files are in boot iSO)

When booting off LiteTouchPE boot ISO system connects to WDS server and then drops after 5 or so seconds. no data is transfer. Proceeds to apply image. (Multicast is not working)
In BDD Logs I see client connect to WDS and then fail "This operation returned because the timeout period expired.".

WDS Multicast has been working for YEARS on our network using MDT boot disk. The update to WADK & WinPE 11 seems to have broken it.

    Hi,

    Thanks for posting in Microsoft Q&A forum.

    It seems to be a known issue. The right way to add WDS multicast to WinPE is to install WinPE-WDS-Tools OC (WinPE optional components) into WinPE. For more detailed information, please refer to the official article:
    Windows Deployment Services (WDS) multicast stops working after upgrading to ADK for Windows 11

    Hope it helps. Thanks for your time.

    Best regards,
    Simon
