As expected when the AutoLab was released people wanted to use it, then found issues. This is why I put version 0.5 on it!
Erik Bussink has found that the Windows 2008R2 build automation for the Domain Controller and Virtual Center VMs is currently only compatible with the RTM release, it fails with the SP1 release showing an error “Windows could not apply unattend settings during pass [offlineServicing]”
For the moment you will need to build the AutoLab Windows servers using 2008R2 without any Service Pack
When I can get hold of the ISO with SP1, and probably a new WAIK kit, I will update the kit and test with various Windows ISOs.
