Can you double check that the OU specified for domain join is getting applied correctly (specifically your "Set AD Machine OU" task)? I'm not seeing any Join OU listed in the relevant section of smsts.log:
[cid:image002.png@01D214CA.7FFB9870] As far as the drive letter issue, would need to see what the partitions in your Format and Partition task is along with the target set for your Apply Operating System Image task. -Phil From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Thelen, Chris Sent: Thursday, September 22, 2016 11:28 AM To: mssms@lists.myITforum.com Subject: [mssms] Optiplex 7010 Windows 10 imaging problems I'm having an issues with imaging Dell OptiPlex 7010s and was hoping to get some help. Issues are only with the Windows 10 task sequence. Everything works fine with Windows 8.1. First issue: 7010s will fail to join the domain when I use a custom Windows 10 reference image. This same reference image works perfectly fine for every other Dell model, it only causes domain join issues for the 7010. The error in the panther logs is that it cannot find a domain controller. If I use the wim file from the Win 10 ISO, then it works fine. I've updated the 7010 driver package with the latest drivers and also updated the Intel LAN drivers to the latest version from Intel. Second issue: When using the Win 10 ISO wim file, everything works fine in the WinPE stages. It formats C drive, applies the image to C drive, but when it reboots during setting up the SCCM client, it switches C drive to X drive and then fails the task sequence as we have steps that are hard coded to point to C drive folders. Same thing as above, this only happens on the OptiPlex 7010. I've attached the logs from running a TS with the second issue. I can provide other logs if needed. Thanks in advanced for any help.
