Just in case the unmanaged switch had STP on it somehow, I had the network admin remove STP (set them as edge ports) from the interfaces being used by the FOG server and the host on the lab switch. Same issue occurs. I doubt there is any kind of NAC/NAP going on.

It’s longer than 27 seconds for it to move forward from the configuring step. It’s at least a minute to a minute and half. According to the Wireshark capture it’s 65 seconds. It’s not world ending, but I think there’s something keeping it from going faster. I just can’t figure out what.

I see some text fly by when it gets past the configuration step. Is there anyway to capture that text?

We did run Wireshark. Once the process hits the configuring (net0 MAC) step there are no packets being sent or received. Once the process ends there is a malformed DHCP packet.

Alright, was able to get the time to do this. I hooked an unmanaged switch up to our lab switch. I hooked the FOG server and the target host up to the unmanaged switch.

Attempt 1: The same thing happens. It passes through the Intel Boot Agent PXE, grabs DHCP quickly, and then chainloads into iPXE 1.0.0 just fine. Then it hangs at configuring net0(MAC) for awhile before successfully continuing forward.

Attempt 2: I disconnected the unmanaged switch from the lab switch. Host was unable to reach DHCP and had no way of knowing how to reach the FOG server.

Attempt 3: I reconnected the unmanaged switch to the lab switch. Then I waited for the first DHCP exchange. When iPXE appeared I disconnected the unmanaged switch from the lab switch. It actually went fast at the configuring net0 step, but only to tell me that it was unable to reach DHCP.

We’ve got a Windows DHCP server setup. FOG is not handling DHCP. Can’t really go into much further detail as I’ve not really been around this place that long.

I don’t mind trying it, however, will I need to enable DHCP on the FOG server when I do so? We had difficulties getting that to work so we just let our network’s DHCP handle it with the network admin’s assistance.

Thanks for the quick response.
FOG version: 1.4.4
Target host: Dell Optiplex 990 (Tried a 755 and an HP Elitebook as well with similar results.)
Built in network adapter on the host: Intel 82579LM Gigabit Network Connection
Using legacy mode.

I believe we used an unmanaged switch at one point. We struggled with DCHP for a bit, but then we’ve moved it to a managed switch on our network. We’re using our network DHCP now. After disabling it in FOG, of course. I could still give it a shot.

We’ve just recently installed a FOG server. It seems to be working so far as we’ve tested, but after chainloading into iPXE it seems to hang at the “configuring net0(MAC address)” step. I feel like it shouldn’t be hanging for 4-5 minutes at this step before continuing on to the menu. I’ve tried different kernals, different hosts, different .pxe, .kpxe, and kkpxe. What am I missing? What is happening at this stage exactly? Driver for the NIC loading?
