SCCM Stopped imaging today 1702 PXE

[PaulWhite@pickens.k12]

So around lunch time today imaging just stopped. I am on 1702 with the update installed and have one primary site server and 24 DP's. One of our techs imaged a lab this morning around 11:00 and when he tried to start another after lunch, the pc's will boot get an IP and when they will download the boot wim and go through the windows start up. Once they get to initialising network connections it just dies, screen goes blank and the computer restarts. I have not changed anything in the boot image but it is the same kind of behavior you get when the boot image is missing the network drivers and since we have 27 different models of PC I doubt this is the issue. It couldn't come at a better time, we have about 15 labs left to image and School starts on Thursday. There are no issue in the console everything looks healthy. I am at a loss, I have read all day and even tried removing PXE from one of my DP's and adding it back. I did run updates on the Site server and database server on Thursday of last week but it stopped today not on Thursday after I ran the updates. Any and I mean any suggestion would be appreciated.

Hello,

Did you try to press F8 before it reboots ?

You will have the log file (smsts.log) in C:\windows\temp.

You can also try to create a boot media and put it on a USB key ...

I did not have F8 enabled on the boot image, but I changed that yesterday. I was looking at my smsts.log this morning and I noticed something strange. If you look right under that line that is high lighted "there are no task sequences available for to this computer.

I just created boot media usb and it does pretty much the same thing, it says no task sequences were found.

Are you seeing this behavior when trying to image known computers and unknown computers? There is a bug right now with computers taking over the Unknown Computer GUID which causes the issue you are experiencing. Do you have this hotfix installed? https://support.microsoft.com/en-us/help/4019926/update-rollup-for-system-center-configuration-manager-current-branch-v Check this post as well. https://social.technet.microsoft.com/Forums/en-US/1a6f8faf-1553-466f-b11c-0f24c6ec23f5/unknown-computers-no-longer-seeing-task-sequences?forum=ConfigMgrCBOSD

I do have the hotfix installed but it does seem very suspect. The reason I say that it just imaged a lab then stopped. We don't image known computers but I could build TS and deploy to some test computers.

Yes, Yes even though I have the hotfix installed it was the "previous" button that got me. I ran the a search for id on all systems and found one with the same id as the unknown x64 computer. Thanks for every ones help on this one. I am connected by VPN but I just imaged a VM and it work fine.
