Sysprep Specialize Shell error

I ran across an issue attempting to sysprep a machine to image.  The %WINDIR%\Panther log showed: 0x8030000b

Some people found that it was issue with Keys, Computer names, Media Center keys improperly included in the unattend.xml file.

In my case, it was caused by manually removing profiles from the machine before sysprep.  Check the registry keys @

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList – perhaps using the Profile Removal utility from system properties is cleaner?
