SCCM PXE Boot Failures: Diagnosis and Step-by-Step Fix
PXE boot failures in SCCM can be a common challenge for IT admins managing OS deployment. This article outlines the most frequent causes of these issues and provides a step-by-step walkthrough to help you diagnose and resolve them.
Common PXE Boot Failure Causes
- WDS: Check for errors in the WDS event logs.
- DHCP: Verify that options 66 and 67 are set correctly for PXE redirection.
- Firewall: Ensure that relevant ports are open.
Checking SMSPXE.log and WDS Event Logs
Start by examining the SMSPXE.log file in the \CCM_LOGS share for error codes that can help identify the root cause of the issue.
Fixing DHCP Option 66 and 67 for PXE Redirection
Ensure your DHCP server is configured correctly to point to the SCCM distribution point using options 66 (BootServerName) and 67 (BootFileName).
Resolving PXE Certificate Issues in SCCM
If you encounter certificate errors during the PXE boot process, verify that your SCCM site server’s certificate is valid and has not expired.
