Hello, well, I'll try to explain my scenario for you. In my network I have a server with A.D. and DNS roles installed, and another server with WDS role, both with Windows 2008 Server. I don't use SCCM, I'm using basically, WAIK, MDT 2008 plus WDS. In my WDS server in workbench all parts necessary are added successfuly, OS, Applications, OS Packages, Out-of-Box- Drivers, task sequences and deployment points. In WDS there is only one boot image "Lite touch Windows PE (x86). I'm having a trouble in windows PE’s automation , I use the Windows System Image Manager to add the Win PE’s image to configuration file and the text file Unattend.xml, but it shows me error messages. The first is about the catalog; The second is an error. It’s seems that Windows PE can’t be updated in the (SIM), I can’t associate the Windows PE image with a answer file, I would like to know if it’s possible to edit edit a Windows PE image to automated information like, username, password and domain. I’m inexperienced with Automating with WDS+MDT and would grateful through help of you. PS: I'm sending the unattend file that is used in automation. Sincerely , Tiago Maraldi Unattend.xml
