SCCM task sequence log file locations

The first step to troubleshoot SCCM OSD Task Sequence issues to is check out the log file – this is called smsts.log.

This can be found in one of several locations depending on the progress of the build and the architecture of the OS:

• Windows PE before HDD format: x:\windows\temp\smstslog\smsts.log
• Windows PE after HDD format: x:\smstslog\smsts.log and copied to c:\_SMSTaskSequence\Logs\Smstslog\smsts.log
• Full version Windows before SCCM agent installed: c:\_SMSTaskSequence\Logs\Smstslog\smsts.log
• Full version Windows after SCCM agent installed: c:\windows\system32\ccm\logs\Smstslog\smsts.log
• Full version Windows (x64) after SCCM agent installed: c:\windows\sysWOW64\ccm\logs\Smstslog\smsts.log
• After Task Sequence has finished running: c:\windows\system32\ccm\logs\smsts.log
• After Task Sequence has finished running (x64): c:\windows\sysWOW64\ccm\logs\smsts.log
