Getting connection timed out on uefi pxe boot when Boot Manager Authentication is enabled

Hi, since PCs are now coming in with only uefi boot options (no legacy) we had to configure everything for uefi pxe booting. The DHCP options were changed. The windows 10 PE drivers were uploaded to the driver share. The drivers for some specific devices were added to kbe_windows_x64. Then a new KBE was created. Each time you boot you select a KBE then it asks for the boot user/pass. After this is entered you always get connection timed out. I have tried changing KBE Network Bringup Delay, multiple different KBEs but the only thing that seems to work is disabling Boot Manager Authentication when imaging which isn't ideal. I do note that when the KBE boots at the bottom of the screen beside option 66 etc it says no data. Option 244 is not set. Any ideas?

  • Can you create a usb boot stick from the same KBE that is listed in your settings under Default SDA Boot Env and see if that boots. Could be bios, DHCP or the KBE
    That will help narrow it down. - SMal.tmcc 1 year ago
  • Yes, that boots to the SDA (bypassing authentication). The options at the bottom still say no data. So, I'm thinking my issue is with DHCP... - JoeB 1 year ago
    • could also be something in bios as well - SMal.tmcc 1 year ago
  • Found it works perfectly on older models. So will update the custom KBE drivers - JoeB 1 year ago

In DHCP check at the scope level for that subnet that the settings are correct.  You can set them at the server level and also at the scope level.  the scope overrides the server level.

option 066 Boot server Host name       (use ip)
option 067 Bootfile name                        ipxe.efi
option 244 Kace option                            (use ip)
