Thanks for taking the time to reply Martyn. We are running 9.5 sp 1. I have not been creating the c:\windows\lddriverstore manually or through provisioning as I was assuming that the HII action was doing this. I am currently using HTTP for my drivers and have allowed the config and other file types in IIS.
I have attached my unattend.xml file to this reply. It is my understanding that the "auditsystem" and "audituser" passes of this unattend are not used at all if my image is oobe /generalized and not audit mode.
