Windows 2008R2 sysprep crashes. Autochk not found

Today I created a clone from a VM that was running. After the clone was completed I disconnected the network card an booted the VM. No problem everything worked. I needed this Cloned VM for a test domain so I syspreped the VM. After booting the VM an error is shown “autochk program not found” after the error a BSOD is shown and the VM reboots.

I started googling and found the solution in the VMware Community pages, see:

The sollutions is simpel, boot the VM from the Windows 2008R2 DVD and go the  command prompt. Type the following commands.

list volume
select volume 1
attributes volume
attributes volume clear nodefaultdriveletter

Reboot the VM and now the SYSPREP continues.
