  • If you are getting a TFTP error, it means that the PXE service has correctly told the client to boot from WinPE, however... The file it told the client to download is not downloading. The WinPE files itself are transferred to the clients using the TFTP service.

    Verify that the TFTP service is running correctly on the server, and that the files are visible to the service. If you need help enable TFTP logging.
