Re: Cannot chain load gPXE to Windows 2003 DHCP

Good day Ron,

Your strange DHCP timeout issues remind me of a situation where multiple
PXE services are racing, and one provides incomplete parameters to gPXE.

With PXE-booting, you've got roughly three scenarios:

1. DHCP provides all needed parameters for a PXE-booting client
2. DHCP and a PXE service live on the same box, where DHCP basically
says, "Ask me for more PXE-boot-specific details on UDP 4011"
3. DHCP lives on one box and PXE-boot-specific parameters are given by a
PXE service listening on another box

The race-like/random timeouts you are getting might be possible to
understand by either tcpdumping/Wiresharking on the same wire (mirrored
switch port or hub), or enabling DHCP debugging in gPXE with:

cd gpxe/src/
make DEBUG=dhcp bin/undionly.kpxe
