: Corrupted PXE configurations on the Distribution Point.
Does the device's current IP belong to a Boundary Group?
Check the time in the BIOS or via the Command Prompt ( time and date commands). Synchronize it manually and restart the PXE boot. 3. Missing or Misconfigured Network Drivers unable to download pxe variable file. exit code 14 sccm
In the context of SCCM PXE booting, Exit Code 14 typically maps to a or "Access Denied" issue during the HTTP/HTTPS request. Essentially, the WinPE environment is asking the Management Point for the policy and instructions (the variable file), but the MP is saying "I don't have it" or "You aren't allowed to see it." 1. Check the Date and Time (The Most Common Culprit)
Have you checked if the client machine when pressing F8? : Corrupted PXE configurations on the Distribution Point
Verify the account is not locked out in Active Directory and that the password has not expired. Re-entering the credentials here and clicking apply can often clear up hidden authentication sync errors. 6. Review Network Ports and IP Helpers
No—this is a misleading error message. In SCCM contexts, it almost always indicates a network connectivity issue during the download of the PXE variable file. The system returns error 14 because it's a Windows system error code that gets triggered when a network operation fails in certain contexts. Synchronize it manually and restart the PXE boot
Use the SCCM console to verify for:
: The default WinPE boot image does not contain the specific network controller driver for the hardware model being imaged.
At this specific stage, the machine has successfully completed the initial PXE handshakes and downloaded the generic boot image ( .wim ). However, right as WinPE initializes, it attempts to contact the Distribution Point (DP) or Management Point (MP) to download the variables.dat file containing your environment variables and task sequence policies. Exit code 14 explicitly maps to a network error that interrupts this operational phase. Root Causes of Exit Code 14
