Deprovisioning failures

I'm getting the following error in the deprovisioning phase of my Windows image:

Relevant info from my template includes:

Is there anything obvious I'm missing here? I took the customization steps from the Windows Managed Image template, and customized the setup script. My setup script runs without error.
