PXE not working suddenly

Question

Everything was working well last Friday, and I had imaged three computers without any issue. BUT PXE deployment stopped working today. I have tried five new computers and got the same error:

PXE Boot aborted. Booting to next devicePXE-M0F: Exiting Intel Boot Agent

The computers could get the correct IP address from my DHCP server, but then failed. What's the next thing I should do to fix the issue?

Thank you! The smspxe.log helps. Below entry shows the correct direction.

After I enable the task sequence, pxe works again.
