I just updated my 2003 unattend/sysprep to include SP1 slipstreamed. Since I did this, now when I begin the sysprep process, along the way it starts prompting me to approve unsigned drivers. These drivers are apparently being enumerated and it prompts me several times and proceeds to go down the list of drivers. I did not originally change anything fromt he original build. Could this be a SP1 thing? Anyway, I have done several things to the winnt.sif and sysprep.inf, aloing with adjusting the security template with no success. Thanks, DJ
