    guys pls help some new Dell laptops at the imaging bench PXE boot, some don't. The failing ones end like this:

    >>Start PXE over IPv4.

    >>Start PXE over IPv4.
  Station IP address is 10.20.40.117

  Server IP address is 10.20.1.15
  NBP filename is
  NBP filesize is 0 Bytes
  PXE-E53: No boot filename received.

>>Start PXE over IPv6.
  PXE-E16: No valid offer received.

Boot Failed. EFI Network.

    same VLAN, same DP. the only difference i can see is firmware settings, but i dont know which ones matter.

    the working and failing machines are teh same model, just bought at different times, some came with different firmware defaults, which BIOS or UEFI settings usually matter for PXE with ConfigMgr? what am i doing wrong??

    hmmm sapnning tree on access ports delays the link coming up, so teh PXE request times out before the port forwards, enable PortFast (or edge port) on client ports, very common after a switch replacement.

    start on the DP with SMSPXE.log (in teh SMS_DP or SMS_CCM logs folder). If u see no entry for teh devices MAC when it boots, the request isnt arriving: its a network problem. If it arrives and says smth like device is not in the database or no advertisements found, its a ConfigMgr targeting problem. hope that helps :)

    if the device was imaged before or is a known computer without an active deployment, PXE will be ignored (abortpxe.com). Make sure the task sequence is deployed to a collection the device is in, available to 'media and PXE', or clear the required PXE deployment for that device.

    yeahhh across subnets, PXE needs IP helpers (DHCP relay) on teh router or layer 3 switch pointing at both the DHCP server and the PXE-enabled DP 🔥 avoid DHCP options 66/67 if you can; they cant serve both UEFI and BIOS clinets correctly. fingers crossed 🤞
