Issue with Lenovo ThinkPads and Secure Boot

Hello guys,

we've been deploying Windows 10 with KACE SDA for quite a while, lately we started to use secure boot. Everything worked fine for workstations (ASUS Mainboard). But we figured out, that we got some problems with deploying to Lenovo ThinkPads. 

Without secure boot everything is working as intended, but we would like to use it. If we start the PXE-Boot it immediatly disconnects and returns to the bootmenu. 

Do you guys know a proper way to troubleshoot this or is there a known issue with the secure boot keys?

Our DHCP is configured as followed:

Option 67 - ipxe.efi

Option 66 - the ip of the SDA

Hi, You can try with this article:

The idea is getting more info of the DHCP/PXE boot process to see if the client is receiving the proper information.

The fact that, without secure boot it works fine, makes me think that there is something missing in the BIOS, maybe a combination of options are needed, so I would check with the vendor (lenovo) to see what they think. See this:

hope this helps
