Deployment not working well

I create a deployment task to image one computer (Testlab). The goal is to use WOL.
When the task starts the pc boots, thats good. But it boots from windows and not from the NIC.
Now i changed the settings in the BIOS, NIC first boot device. Now the pc boots and connect to the
PXE server. But the pc is waiting for deployment and waits for days??!!. Nothing is happening.
What do i wrong.

Is het oke to set the NIC as a first boot device? Everyrime the pc boots it's gonna make a conncection to PXE server and that's not what i want.

Regards,
John
