But the PXE service responded back only with the block size agreement, with no confirmation on the window size. Notice that the device said “I can support a 1468 block size” and for whatever reason it initially aborts the transfer before making the actual read request with the block size and a window size of 4. The device will then do a TFTP file transfer (using UDP): Right after that, the device will send out a proxyDHCP request directly to the PXE server (as it kept track of the IP address of that from the second DHCP Offer packet, the one with the PXEClient identifier):Īnd the PXE server will respond with a proxyDHCP Offer directly to the device, specifying the TFTP server and file name that the device should use to boot: The device will then send a DHCP Request packet to officially request the offered IP address from the DHCP server, and the DHCP server will respond with a DHCP ACK packet to confirm that the IP address has been reserved and can be used by the device. And while in theory you could run DHCP and PXE on the same server, that changes the process, so don’t do that.) That second response doesn’t offer an IP address, but rather just indicates that “yes, I am available to help you PXE boot”: If those servers are on a different network segment, that means BOOTP forwarders/DHCP helpers. (You need to have your network configured appropriately for both the DHCP server and PXE server to see the broadcast packet. The second response comes from the PXE server, which saw the initial DHCP Discover request. The device then gets two different responses to that DHCP Discover request, with the first from the DHCP server (10.102.1.1) with an IP address that it can have (10.102.1.124): In that request, it indicates via the “Vendor class identifier” (option 60) that it wants to do a PXE boot by specifying the “PXEClient” string:

The device sends out a DHCP Discover request, asking a DHCP server for an IP address. So after you press enter to select that option, what happens? Here’s a Wireshark capture that shows the conversation: In the image below, I’m using Proxmox/QEMU (pressing Esc during startup and then navigating to the boot menu), where I can choose PXEv4 (PXE over IPv4): Dell uses F12), but once you see the menu, you can choose the PXE option.

So it will PXE boot when it starts up, install an OS, and then continue to run that OS from the hard drive, at least until I want to do it all over again by reverting to the checkpoint.) The key that you press depends on the hardware (e.g. (On VMs, this can get tricky, so what I typically do is create a new empty VM with the hard drive first and network device second, then create a checkpoint with the VM off in that state. So, you have to press a key to choose a temporary boot device. Most of the time, that doesn’t include network booting (certainly not before booting from the hard drive, as that would prevent the locally-installed OS from running automatically). When a device with an Ethernet connection boots up, it will process the entries in the boot order. And I specifically don’t say “PXE booting” in that context, because we can do more than that. So, we built the Tanium PXE service.įor the rest of this blog post, I want to focus on the technology needed for network booting. It’s fine to boot from a USB key (and necessary in some scenarios, something to discuss later), but powering on a machine and pressing a couple of keys is much easier. =" back on 10/30.When we started working on Tanium Provision, one of the things we needed to build was a mechanism to do network booting. I'm looking through the SMSPXE.log and the last entry I see just says "= PXE Provider shutdown.

I feel like there must be something obvious I'm missing here. Updated and distributed the image to the same distribution point as aboveĬreated a task sequence "Install an existing image package to a virtual hard disk" with the above (64-bit) boot image and OS image - no applications, added to a workgroup, set an admin password, set my product key, used the default ConfigMgr packageĭistributed task sequence to distribution pointĭeployed to "Unknown Computers" collection as "Available" and available to "Only media and PXE" without setting any deadlinesīasically, the VM boots up to PXE and never finds anything.

Updated distribution point (I only have one anyway) and distributed content for each of the default boot imagesĪdded an OS image (the install.wim file) from a Windows 10 version 1703 ISO Trying to set up a bare Windows 10 image on a brand new VMWare VM with a VMXNet 3 adapter. New to all of this so forgive me if I'm being ignorant here.
