#3 and #4 might be your problem. If your TS is deployed only to All Systems then only machines that already exist in SCCM will see it. A computer unknown to SCCM will not be a member of All Systems.
If your machine is unknown to SCCM then it will not see your task sequence. When you attempt to PXE boot SCCM will first check to see what task sequences are deployed to collections that the machine belongs to. If one is found then SCCM will allow it to PXE boot. In your case since the machine is unknown to sCCM and your task sequence is only deployed to All Systems SCCM will not allow it to PXE boot. Deploy your task sequence to the Unknown Computers collection. Then try it. From what you describe I think that should get you going Mike From: [email protected] [mailto:[email protected]] On Behalf Of David McSpadden Sent: Wednesday, January 21, 2015 8:34 AM To: [email protected] Subject: [mssms] RE: SCCM 2012 R2 and PXE boot 1. Just the default x64 image on the PXE enabled DP. 2. It is assigned to this sequence. (Using Windows Noob set of instructions.) 3. It is deployed to all systems. 4. Unknown machine at this point. Reviewing the SCCM 2012 server. WDS is getting a 1067 when trying to start. No WDS, no PXE. GoogleFU shows KB2905002 helps but that hotfix is unavailable at the moment from Microsoft. PXE-032 TFTP timeout PXE- Abort ^ Makes sense with WDS being down.

Are you getting a PXEAbort, or is it attempting and the boot process is failing at some point? Some basics to check. 1. Do you have both the 64bit and 32bit boot images on your PXE enabled DP? 2. Is one of those boot images the one assigned to your task sequence? 3. Is your task sequence deployed/advertised to a collection? 4. Is the machine you're trying to PXE boot a member of that collection?

My PXE boot on my workstation sees my DHCP server. I have added 066 and 067 to the DHCP options but the workstation fails to boot. It gets an address from the DHCP server then it trys to TFTP?? Then it fails. I see it in the DHCP lease but I see nothing in the SMSPXE.log on the SCCM 2012 server?? I have never booted to PXE in the past so I am a total virgin in this area.
