Midiboy, I feel your pain. I have escalated this to Microsoft since we have some reps where I work and they hopefully have been looking at it this weekend and can have an answer as to why the SP1 slipstreamed build is so jacked up and a solution. As a backup plan, I am going to use my 100% functional Pre SP1 build with my XML that has been working on all vendors hardware for months now. I am going to install SP1 standalone silently after OOBE at login screen, adding a runonce reg key to install using setupcomplete.cmd to execute and using one more autologon launching a VB window up about the install and forcing a restart after the first part of the install. lol this sounds like the best way to go, it's only 444MB so not to bad. I'll let you guys know if these Micorosft guys come up with anything. Does anyone know if it is suggested to install after OOBE or is it better during audituser phase or another phase?
