Systems Deployment

I created a Win7 with all updates WIM image.  I downloaded the sysprep creator software, built the unattend.xml file and placed the file in the sysprep and panther folders.  When I sysprepped the image, I used the audit, generalize and shutdown options.

When I deploy my image, I added the GetComputerx64, Create Single Partition, Format/MBR C: in my pre-install tasks.  My mid-level task is Set Computer Namex64.

These tasks work flawlessly with my basic Win7 image and scripted install.  When I deploy my "Win7Update" image and type in the computer name at the prompt, the computer name is not the same as what I typed in.  I get no error message.

Do the Windows updates do something weird to the Get/Set computer name task?

Thanks for your help!
