PXE boot error KACE
I'm facing problem PXE booting on multiple Lenovo Notebook even though all the settings in the BIOS are correct (Secure boot disabled and the boot order is set correctly and the BIOS is up-to-date) I tired both on UEFI its says "NBP filesize is 0 bytes" and then "PXE-E23 client received TFTP error from server" and when i try legacy it says "NBPf ile is too big to fit in free base memory". It works fine on any other machine except for Lenovo machines.
Any Idea what might be causing it?
Any suggestion/solution is much appreciated.
at first: try to update to the latest BIOS versions.
Which model(s) are affected? Vendor, Make, Build, BIOS version.
Sometimes the bootcode is problematic and needs to be fixed from the vendor. You can check with the vendor if they have issues with PXE boot.
As a workaround is using a USB KBE.
Check the firewall. We had the same error when we changed from legacy to uefi boot and the problem was that the restrictions on the firewall was to high. We opened the ports (1024 to 65535) for in- and outgoing traffic and everything was fine.
The inital communication starts on the lower portrange (https://support.quest.com/de-de/kb/129799/network-ports-needed-for-the-kace-systems-deployment-appliance-sda-) and then an dynamic port is used.
