Create Task Sequence Media Failed (CreateMedia.exe Error 80070003)

Hello,

because SCCM 2012 R2 SP1 is not able to create Task Sequence Media for bigger images, I had to try to use workaround found here: http://blog.ryanbetts.co.uk/2014/07/sccm-2012-r2-create-task-sequence-media.html

But when I do that, it always fails. I run following command:

"C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\i386\CreateMedia.exe" /K:Full /P:"GRCZSRVV0113.grafton.local" /S:"CEN" /D:"GRCZSRVV0113.grafton.local" /L:"Configuration Manager 2012" /A:"CEN00146" /Z:False /T:CD /M:10240 /F:"C:\SCCM\SCCM.iso"

But it always end with:
