Location logfiles during Task Sequence WinPE

During the Task Sequence you can check for a log file smst.log which allow you troubleshooting of operating system failures:
It depending on deployment phase, SMSTS.log file will have the location below:

Logfile

During OSD

Phase Location
Windows PE (WinPE) -Before the harddisk is formatted and partitioned x:\windows\temp\smstslog\smsts.log
Windows PE (WinPE) – After harddisk formatted x:\smstslog\smsts.log and will copied to C:\_SMSTaskSequence\Logs\Smstslog\smsts.log

After OSD and when the Operation System is installed

Phase Location
Operating System – Before SCCM agent is installed C:\_SMSTaskSequence\Logs\Smstslog\smsts.log
Windows 32 bit – after SCCM agent is installed C:\windows\system32\ccm\logs\Smstslog\smsts.log
Windows 64 bit – after SCCM agent is installed C:\windows\sysWOW64\ccm\logs\Smstslog\smsts.log

After Task Sequence is complete

Phase Location
Windows 32 bit C:\windows\system32\ccm\logs\smsts.log
Windows 64 bit C:\windows\sysWOW64\ccm\logs\smsts.log

Best practice

You can copy the SMSTS.log file to a USB key for troubleshooting.
When the error appears in WinPE, click on F8 to display the command prompt window.

Use xcopy to copy the logfile from local to usb key.

SCCM Cache Size

By default, the cache size on 5120 MB. If there is more data are needed because the total size of the MSI files is more than the default cache value, then you can adjust the size during the Task Sequence. The size of the Cache is to match by first making an application or Package in SCCM. With SCCM 2007 you could in the Task Sequence by setting the command of the Client installation.

However, this doesn’t work more with SCCM 2012.

To the Cache as an example we use the cache size 99999

Dim client

Set oShell = WScript.CreateObject (“WScript.shell”)

Set client = CreateObject(“UIResource.UIResourceMgr”)

Set CacheInfo = client.GetCacheInfo CacheInfo.TotalSize = 99999
