Trying to generalize with SysPrep (although all the PCS are the same anyway so perhaps I should leave this out)
Sysprep was not able to validate your windows installation. Review the log file at %WINDIR%\System32\Sysprep\Panther\Setupact.lod for details. After resolving the issue, use Sysprep to validate your installation again.
But as far as I can see there is no log file...?
There is a setuperr.txt but I do not have permission to open it.
