Today I had “The Case of the Missing PXE Advertisement” with a PC.
Bit of background – I’ve an OSDeploy device collection which has a zero touch MDT Task Sequence deployed to it, advertised to PXE and Media only, and set to always rerun program. So anything in this collection will automatically get the deployment. Infinite loops are prevented by the “PXE Deployments” flag that is automatically set on computer objects once they have started a PXE deployment. To re-image a PC I just drop it back in the collection and clear the flag.
I’ve also got one which prompts for the computer name, advertised as optional to all Unknown Computers. New kit I boot to this and put the name in and off it goes.
