Symptoms
Error appears when you try to PXE boot a computer, resulting in abortpxe or PXE Boot Aborted.
Checking SMSPXE.log on the Distribution Point, it reads something like
no advertisements found
No boot action. Aborted.
Cause
SCCM has no task sequences advertised to this computer.
Resolution
For computers straight ‘out of the box’, ensure you have a task sequence deployed to the Unknown Computers collection, and that it is enabled for PXE Clients.
For computers known by SCCM, if you have a specific Collection for deploying computers make sure the computer is a member of that Collection. Otherwise, check your Task Sequence deployment configuration to ensure it is enabled for PXE Clients. If you do not use a specific Collection for deploying images other than the Unknown Computers Collection, delete the computer from SCCM for the advertisement to be picked up.
