I am on Landesk 9.5 SP2. It gets all the way past CTOS but fails when booting. I look at unattend.xml of the pc and it looks like the varaible %Serial% is not passing correctly. In the Computer name section of the unattend is "Computer"."System"."Serial Number". Not sure why this is happening. I'm going to test another machine but this is odd. Any help would be great.
