So lets start with some data collection.
Is the dhcp server, fog server and target computer all on the same subnet/vlan? If so we can use the fog server to help us see what is going on in the pxe booting process.
I have a tutorial here on how to use tcpdump from the FOG server to capture a pcap file of the booting process: https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue
If the dhcp server, fog server, and pxe booting client are on the same subnet/vlan then go and grab the pcap and post it here. If any is on a different vlan then give us an idea of your network design so we can come up with a useful plan to collect this information.

@george1421 yes there are all on same subnet/vlan
Here you go sir0_1542402185175_output.pcap10.24.32.60 is the ip the host pulled from dhcp

@Raymond-Bell Ah found it.
You actually have 3 dhcp servers responding. If you use wireshark and inspect the pcap file at patch #19 There is a dhcp server 192.168.15.1 that is giving band info. The other 2 dhcp servers 10.24.31.232 and .230 are in harmony. The 192.168.15.1 appears to be a cisco router on the surface.

@Raymond-Bell That 192.168.15.1 looks like its a real device on your network in that its giving the correct domain name, but its subnet mask and IP address range is not compatible with the rest of your network.

You mean I was kind of on the right track? Lol. Yay me! I just don’t do all the fancy pcap stuff sorry.
Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

That is why we are here to help. I’m glad you have it worked out. Something simple, but it caused you so much problems. On the plus side you are now on 1.5.5 with all of the fixes, so you are in a better place than when you started the day.
