SCCM 2012 R2 - Capture Media - sysprep remains executing

Hi,

I am using SCCM 2012 R2.

I have created the capture media using x86 boot image. The PC to be captured is Windows7x86PRO Spanish.

The problem is that sysprep remains executing (aprox 1 hour before I manually shutdown), and never restarts the PC for image capture.

The errors at smsts.log are:

Set command line: "C:\Windows\system32\sysprep\sysprep.exe" /quiet /generalize /oobe /quit    PrepareOS    13/12/2013 13:19:19    2852 (0x0B24)

I Have used the same CD to capture another PC (different manufacturer, same Windows and software) and the sysprep was OK and the image capture was OK.

Please your help.

Thanks in advance!
