SCCM (System Center Configuration Manager) is a system management software developed by Microsoft that allows users to manage large groups of Windows-based computers. SCCM's PXE (Preboot Execution Environment) feature enables administrators to access the Windows Preinstallation Environment (Win PE) across the network, making it easier to manage and deploy Windows-based systems.
In cases where a computer fails to boot, a bootable CD or USB drive is often used as a rescue tool. However, this traditional method is not practical when the computer lacks a CD drive or USB port, and it's also inefficient for managing multiple computers, requiring manual insertion and booting of the device for each machine.
Fortunately, SCCM PXE boot allows users to use network boot multiple computers. However, many users experience issues such as SCCM PXE boot aborting, not receiving the boot image, etc. The main reasons for these issues are IP Helpers and PXE installation and configuration problems.
Regardless of the cause of SCCM 2012 PXE boot not working, you definitely want to solve this problem immediately. Then these two approaches are for you.
🌟If you're looking for a more effective solution to boot multiple computers, consider using Qiling PXE Boot Tool, a reliable network boot option.
If all the necessary components for a PXE boot are on the same network or subnet, IP Helpers do not need to be configured.
If the DHCP server, client computer, ConfigMgr server running WDS, and PXE-enabled DP are on separate VLANs or subnets, you must configure IP Helpers on the routers to enable PXE booting.
The configuration of IP Helpers on routers varies by manufacturer, so it's best to consult the manufacturer's instructions for correct setup. If SCCM PXE boot still doesn't work after this, try the next method.
Step 1. Clear the Enable PXE checkbox on the DP. Select Yes when you're prompted to remove the WDS.
Step 2. Use Distmgr.log (for DPs on site server) or Smsdpprov.log (for standalone DP) to verify that PXE was uninstalled.
Step 3. Verify that WDS is uninstalled on Server Manager. Then restart the server.
Step 4. Locate and delete the RemoteInstall folder.
Step 5. Modify the date on the self-signed certificate in the properties of PXE DP, then wait for the new certificate to be created.
Step 6. Install WDS via Server Manager.
Step 7. To reinstall the PXE point, select the check box in the DP properties, and monitor the installation process using Distrmgr.log or Smsdpprov.log to verify that the DP was successfully installed.
Step 8. Verify that there is a new Remoteinstall folder.
Step 9. Distribute at least one x64 and one x86 boot image to the DP, and ensure the PXE option is enabled for each, as x64 boot images are required for UEFI PCs or BIOS PCs in Legacy mode, even if all PCs are x64.
Step 10. Make sure that the WDS service was started.
Step 11. Verify that the following SMS folders were created after navigating to the RemoteInstall folder:
Step 12. Open the SMSImages folder and verify that all boot images are listed here, sorted by Package ID.
Step 13. Open the SMSBoot folder and verify that both the x86 and x64 folders are populated with files.
Step 14. Now, you can try a PXE boot.
These methods resolve most problems that affect PXE boot, including SCCM PXE boot not responding. However, they are very complicated and time-consuming, requiring careful execution to avoid potential issues.
If SCCM PXE boot fails, consider using an alternative that works better. Luckily, Qiling Disk Master Workstation offers a solution with its Qiling PXE Boot Tool, which provides all the functions of SCCM PXE boot without requiring modifications to existing DHCP servers or routers.
This utility enables you to boot client computers within a LAN from a bootable micro-system you create, and also allows you to create a bootable disc if needed. Unlike some other tools, it runs smoothly on Windows 11/10/8.1/8/7/Vista/XP, and its ease of use makes it a great option. You can simply download the free trial to see how it works.
Tips:
Fixing SCCM PXE boot issues can be done in two ways. Alternatively, using Qiling PXE Boot Tool is an even better option, as it also enables client computers to boot from the network using PXE, making it easier to operate. This can help reduce daily workloads with Qiling Disk Master Workstation.
