Apply Operating System: Download() failed. 80072efe


If you get this error try adding this command line to your task sequence

cmd.exe /c Wpeutil disablefirewall


let me know if this workaround helps.


Task Sequence can't find a dependency that doesn't exit

When I see 'Failed to run Task Sequence - This task sequence cannot be run because the program files for XXXXXXX cannot be locataed on a distribution point'

I go to Monitoring \ Distribution Status \ Content Status. It's the quickest way to search all package objects. Today the search came up with no results.

I exported the task sequence to make sense of it, found the ID in a section about OSDSubTaskSequenceTsReferencePackages -

<variable name="OSDSubTasksequenceTsReferenceApplications" property="TsReferenceApplications"></variable>

<variable name="OSDSubTasksequenceTsReferencePackages" property="TsReferencePackages">ZZZ00019,ZZZ0001F,ZZZ00020,ZZZ00024</variable></defaultVarList></subtasksequence>


What happened was someone removed a driver package and deleted it. The main task sequence still referenced it. To fix I modified the main task sequence, so it kicked off new policies.




SCCM USB Boot disk creator


I made a little program that sets up usb drives to be bootable into OSD winpe. I made it because we are getting devices without dvd drives that can't pxe boot and our techs don't have access to create bootable usb's from the console as they need the dp cert and password.

You generate a boot iso from the console, then copy the cd contents to the source folder where the program resides.

Program and my bad source code (if anyone wants to improve it)[1]

Dot Net 3.5
A bootable iso generated from the SCCM Console

Copy all files from the bootable iso to the source folder that resides with the exe.
Distribute as you wish.
