Issue with creation of PXE image in DS 6.9

Hi All

I have an isuue on DS 6.9 SP6 with WinPE 4. When I boot on PXE (WinPE 4) it fails with exit boot image. When i look iin the PXE\Images folder i got Menuoption131.tmp even after the bootwiz is finish. When i rename the folder to Menutption131 it works fine. 

What is the issue here?

Kind Regards
