"Just because you can PXE boot does not mean there are Task Sequences advertised. It just means you have your boot images setup."
- Acutally, when pxe booting it will check to see if there is a TS deployment available to that machine, if there is no deployment it will abort the pxe process and not go on to download the WinPe image. Mike, I assume you've checked to see if this happens on different hardware types? We have seen in the past after booting to WinPe on some machines they took just a bit longer to fully initialize the network driver, so if you clicked as soon as the gui was available to get the list of TS's it would fail.

Just because you can PXE boot does not mean there are Task Sequences advertised. It just means you have your boot images setup. Open Config Manager, navigate to Software Library>Operating Systems>Task Sequences. In here should be your Task Sequences. Click on one and check its deployments via the Deployments tab at the bottom. This is who it is currently advertised to. If need be, you could deploy it (advertise) to another Device Collection.. when doing this, DO NOT set it as Required unless you want to wipe everything. Rich From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Marable, Mike Sent: 14 January 2015 14:53 To: SMS Subject: [mssms] CM12 - No Task Sequences Available?? For the third week in a row something has knocked out OS deployment offline. We can PXE boot a machine but during the boot it will suddenly reboot out of WinPE and back into the full OS. We can pop a command window to prevent the reboot and the SMSTS log has this right before it bailed out and attempted to reboot: "There are no task sequences available to this computer.. Please ensure that you have at least one task sequence advertised to this computer. Unspecified error (Error: 80004005; source: Windows)" If there were no sequences advertised then SCCM wouldn't allow it to PXE boot in the first place. I boot a machine using SCCM boot media and when I hit Next on the welcome screen I get the message that there are not sequences available. SMSTS log : "No assigned task sequences" There are no other errors in the SMSTS logs on the clients. The site status within SCCM shows all green as well. Now this has happened three weeks straight now. It first happened New Year's Eve, then Thursday of last week and now again this morning. It starts around 9:00 am and magically corrects itself within 2-3 hours. We've checked out networking, DNS, WINS, the SCCM guys say that there are no external process running (like backups, virus scans, etc.) on the infrastructure at this time. It's maddening since it magically starts and magically corrects itself and we cannot figure out what is causing it. Within WinPE we can ping the Management Points, in fact we can ping all of the SCCM servers. Machines that are already in the process of building continue to do so and do not fail. Also, any non-OSD deployment will still work during this time. We can pull deployments, even non-OSD task sequences will run. So whatever is causing the problem is only affecting machines attempting to start an OS deployment. Anyone else ever see anything like this?
