Windows could not apply unattended settings during pass (null).
When trying to deploy a Windows 7 image from WDS I was confronted by the above error. The error occurred whilst trying to deploy different Windows 7 images to different computers and laptops.
After routing through log files and the internet I was starting to get a little frustrated. At this point I thought that I would try using the install.wim that comes on the Windows 7 CD to see what happens. Whilst browsing the \sources folder on the CD I noticed the boot.wim file. Now, although I have never needed to add multiple boot.wim files for the assorted OS’ I already deploy off this WDS Server I thought I would add the boot.wim (right-click Boot Image in WDS and select ‘Add Boot Image’. I labelled the new boot.wim file to ‘Windows 7 Deploy’ on import and then chose this option when PXE booting the Laptop.
Hey presto, it now works without any errors.
Hopefully this will save someone the headache I received getting to this point.
Good luck
Neil



Much obliged!
This seems to be the answer allright. Could install 2 types of different Windows versions to the computer without any problems after loading a different boot image on the WDS server.
And that after searching quite some time on the internet en testing and tweaking and testing again my WDS server.
Thank you, thank you & thank you! Now I just need to get the bleeping answer file to work right!
Thank you so much. I have been looking for this fix for 3 days and stumbled across your post. It worked for me too! I am deploying Windows XP, Server 2003 for training in the Army and we will be moving to Server 2008 and Vista or Windows 7 soon. I got all images working except 7. I had the same problems you did. Thanks for posting the answer.
Glad I could help.
Regards
Neil
