I had to install the PXE Service Point and WDS.
After that the WDS service started successfully.
But I added Broadcom NIC driver to the x64 boot image and updated the DP, the WDS crashed again:
Faulting application svchost.exe, version 5.2.3790.3959, faulting module wimgapi.dll, version 6.1.7600.16385, fault address 0x0000000000032a8e.
Now, I have to install the PXE Service Point and WDS again.
