As Microsoft has recently released to MSDN/Premier/TechNet customer, I started to create unattended installation file to use with WDS.
After multiple try with error when feature were enabling (error in offlineservicing), I finally discovered this was due to NetFX3 feature I tried to enabled.
Already during the beta stages, there was lot of issue while enabling .Net Framework 3.
I currently have no solution to enable .Net Framework 3 in an unattended Windows installation.
This is really annoying to have such BUG with an RTM product !!!
Come on Microsoft, provide us some finished product!!!!
