The computers on our office building are (via BIOS) configured to boot PXE as first option.
This is a useful setting, as long as, when needed, we can remotely restore non-booting machines and all that stuff.
But, if someone sets up a rogue PXE server, machines could be compromised at next reboot (i.e: automatic Windows reboots), so being able to detect such server is a must.
What methods could I use to test if there is any PXE Server running on my local network?
If possible, obtaining some info (like IP or MAC) to locate this rogue server could be fine.
- The network already has a DHCP server running. PXE and DHCP server are not on the same device/computer.
