For instance, I'm in the midst of reimaing a lab of 40 computers. I have all computers set to PXE boot. They all boot and I select the option for snap deploy. All of the 40 booted into it and got to the screen where they were waiting for the deployment. But two computers would wait about a minute or so and then reboot. Also, they weren't showing up in the admin console. I've been using this product for a year now and just learned to live with it. My work around is, when the image of the lab is done, remove the hard drive of the computers that don't work (which is usually one or two per lab), and put the hard drive in another identical computer and reimage it and put the hard drive back when done. I have found that computers won't boot at all to PXE if the onboard NIC is bad and we've replaced it with a PCI NIC. But all the computers in this lab are almost brand new and none have the NIC replaced. How would I go about troubleshooting why the two computers wouldn't stay booted to the PXE server? It has to be NIC or computer motherboard or chip related.
