    My initial reaction is that you have 2 dhcp servers on your network.

    If your fog server, dhcp server, and pxe booting client are on the same subnet, we can use the FOG server to eavesdrop on the pxe booting process to tell us what is going on.

    Please follow these instructions: https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue

    Upload the pcap to a google drive or drop box and post the link here. If you don’t want to post the link in a public forum, send me an IM and we’ll take a look at it. The captured file will tell us the actors in your pxe booting play.

    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!

      I agree with George.

        @CMTprj Maybe that Hyper-V network adapter is set to NAT instead of bridged. If not then follow Georg’s great post.

        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

          We are currently using the undionly.kkpxe file instead of undionly.kpxe to boot Hyper-V Gen1 /bios VMs. This file is also working correctly for the physical hardware that we have tried it on so far.

            Thank you for the help. I used Wireshark and found my rogue DHCP server. Turned out to be an AudioCodes SIP Appliance that was recently added to our network. I have that disabled and now when my Hyper-V GEN1 virtual machine boots it is asking for the TFTP server ip address. 0_1503993659620_have to type in TFTP IP.PNG
            This is not the behavior I want… When I do type in the address if times out

              @cmtprj If iPXE asks for a tftp server then your dhcp server isn’t filling out the pxe boot request correctly. You need to have the next-server and boot-file fields set correctly in the dhcp offer header.

              What device is your dhcp server?

                I am using a Windows 2016 server for my DHCP services.

                  @cmtprj if you can, is it possible to get a pcap of the exact communications where you need to key in the tftp IP address? There is something going on there that we need to understand.

                        Sorry for the late response. I have not solved the issue but I also need to get some other items finished. I believe the root cause in this situation is not FOG but SCCM getting in the way. I might not have time to circle back to this until next month. I am leaving for our Florida office in a few days to help with things down there and attending Microsoft Ignite that last week of the month.
