SCCM 2012 R2 Tasksequence for VDI Master Image

Question

Hi
I'm currently building a ConfigMgr Tasksequence for a RDS VDI solution. At the end of the TS I have a PowerShell Script which prepares the SCCM Client for the master image (delete certs, remove provisioning mode). I would like to use the variable
SMSTSPostAction for doing the sysprep with a shutdown. But the  machine hangs after rebooting out from the PS Script. Of course the Agent is no longer available but the SMSTSPost Action Variable should start.
Does anyone have an idea?
I need to use SCCM as MDT is not an option.

I fixed this by myself using powershell.
At the end of the TS I copy a PS Script to the sysprep folder. This script is running as SMSTSPostAction and does the following:
# Step 1 -Prepare SCCM Client for VDI Deployment
Get-Service -displayname "SMS Agent Host" | stop-service -Force
Remove-Item -Path C:\Windows\SMSCFG.INI -force
Get-childitem -Path cert:\localmachine\sms -DnsName *SMS* | Remove-Item
Invoke-WmiMethod -Namespace root\CCM -Class SMS_Client -Name SetClientProvisioningMode -ArgumentList $false
Clear-Host
Write-Host "Please do not use the VM. SMSTSPostAction is still running!" -foregroundcolor Green
Write-Host "Waiting several seconds until Sysprep..." -foregroundcolor Green
Start-Sleep -s 60
# Step 2 - Sysprep & Shutdown
C:\Windows\system32\sysprep\sysprep.exe /generalize /oobe /shutdown
The Maschine reboots at the end of the TS with a success code and runs then the SMSTSPostAction. The SCCM Agent is then well prepared for cloning. Make sure you have set your execution policy right.
