Unable To Download Pxe Variable File. Exit Code 14 Sccm File

Modern hardware ships with UEFI firmware, but many boot images are still x64 BIOS-compatible. If there is a mismatch, PXE might load the initial network stack but fail when trying to access variable storage due to driver or memory addressing issues.

Check:

Located on the PXE-enabled Distribution Point.

While the error code suggests a download failure, the root causes generally fall into three distinct categories: Authentication and Certificates, Network Communication (Firewalls and Ports), and Configuration Drift. unable to download pxe variable file. exit code 14 sccm

The most common cause: The boot image required for the architecture (x64 or x86) is not distributed to the distribution point (DP) acting as the PXE server.

How to check:

Why this causes exit code 14:
If the boot image WIM is present but its associated policy or variable file components are missing on the DP, the client can boot into WinPE but cannot retrieve the variable file because the DP cannot generate or serve it. Modern hardware ships with UEFI firmware, but many

Over time, configuration settings in SCCM can drift or become corrupted.

In some cases, the client has a stale PXE advertisement stored in WMI. Delete the device from SCCM (if it’s not critical) and let it re-register. Alternatively, run: Clear-PXEAdvertisement.ps1 (community script) or manually delete the SMSPXE folder under SMS\DATA\.

If you want, tell me the PXE DP logs’ relevant SMSPXE.log lines (timestamped) and I’ll map them to the likely root cause and next action. While the error code suggests a download failure,

This is the most frequent solution. If a previous attempt failed or was interrupted, the cached files on the local hard drive or RAM disk (X:) can become corrupted, preventing the new variable file from writing correctly.
