No Config File PXE

No Config File PXE

Machines are not finding configuration file, when i try to use PXE.

I have configured option 66 and 67.
No other PXE is installed.
Components have been uploaded.
PE image created and uploaded.

Machines will say they are downloading bootwiz.cfg but then indicate that no config file was found.
