MDT2012 : I'm lost with "[C:\Windows\Panther\unattend.xml] for pass [specialize]" error

Hi,

i have a weird error with MDT2012 during a W7 SP1 x64 (full update) install, after hardware detection. I use WDS with x86 PXE on W2008R2.

"Windows could not parse or process the unattend answer file [C:\Windows\Panther\unattend.xml] for pass [specialize]. A component or setting specified in the answer file does not exist."

My sysprep & image capture is fine, without any error. I just want to deploy my production computer.

Here is my BDD log. It seems fine for me :-(((

I'm totally lost !!

Thanks you,

Francois
