    UEFI PXE Boot issues - PXE-E99: Unexpected network Error


      Good Day,


      I'm not sure what caused my issue, but I'm unable to PXE Boot from UEFI (this worked in the past)

      Running 9.6 SP1


      I have tried re-deploying my PXE rep with no luck

      The issue may have started when we patched to SP1 or possibly after adding a driver to the WinPE image... Did this via the "Preboot" menu in the console (Although the error does not seem related to boot_x64.wim)

      Unfortunately our techs just switched to legacy as a workaround so I don't know when the issues surfaced.


      This pops up very briefly on the client:


      Server IP address is   
      NBP filename is EFI\UNDI\BStrap\bootx64.0
      NBP filesize is 1615872 Bytes
      Downloading NBP file...

      PXE-E99: Unexpected network Error.


      I have confirmed the existence of the file on the server in the following path. 

      C:\Program Files (x86)\LANDesk\PXE\System\images\EFI\UNDI\bstrap\bootx64.0    2014-06-19 5:17AM   1,578 KB


      The hash date matches the file time stamp.





      Tried dropping the firewall on the Server, Rebooting and yelling  "Work darn you!"


      Has anybody encountered this before or know what logs might help me come to a solution?


      Thank you,
