Here is my issue:
If I launch an OSD Task Sequence from USB, CD, or PXE the OS image is downloaded via multicast, which is what I want.
If I launch the exact same OSD Task Sequence from the Configuration Manager Client (which is set to download the same bootable WinPE then reboot into said media) the OS image is downloaded via UNICAST.
Can anyone explain why this is and if it's possible to fix it? I don't understand how running the OSD Task Sequence from the Config Client would make a difference since it's just downloading the same WinPE environment used from PXE or a Flashdrive.
