How to fix: “NBP filesize is 0 bytes” when PXE booting. PXE-E23 error.

Date : September 6, 2018


When attempting to PXE boot a UEFI machine, the following error is displayed:

NBP filename is boot\x64\wdsmgfw.efi
NBP filesize is 0 Bytes
PXE-E23: Client received TFTP error from server



Copy "C:\Windows\System32\RemInst\boot\x64\wdsmgfw.efi" to “<WDS root>\Boot\x64\wdsmgfw.efi

This error is caused by wdsmgfw.efi missing from <WDS root>\boot\x64\ directory.

It’s not working… I still get the same error.
You say “paste in ‘\Boot\….’
But what is the path of WDS root ? c:\RemoteInstall ? c:\DeploymentShare ?
I tried both and still get this error.
