Lenovo M73 network fails on FOG OS boot

  • I have several Lenovo M73 MT-M 10B7-S01900 desktops. I am using one as a FOG server and trying to manage the others as clients. The clients successfully PXE boot to the FOG menu but when attempting to register the clients I get the following error:

    starting enp2s0 interface and waiting for the link to come up
    failed to get an IP via DHCP! tried on interfaces(s): enp2s0
    please check your network setup and try again

    FOG Version: 1.5.9-RC2
    Note: the fog server is dual-homed interface enp2s0 is on the isolated imaging network ( and the other on the main LAN ( The imaging network is using FOG DHCP.

    Other machines, including Lenovo ThinkPad t500, DELL Optiplex 9020, register successfully.
    The M73s also successfully register on another FOG server on a separate network (single-homed with separate DHCP/DNS) that has been upgraded from 1.5.8 to 1.5.9-RC2.

    Does anyone have any tips on where to start troubleshooting this?
