Hi, I have a combo installation disk of Windows 2003 Standard/Enterprise from MSDN subscription services and I can't find any information out there on how I can slipstream either to SP1. I've tried the I386 folder for each STANDARD and ENTERPRISE and also I've tried both :s and /integrated commands but I keep getting "Failed to copy all or some of the files nessisary for an integrated install." error. Has anyone done this before? My TechNet searches didn't come up with anything. The disk is structured like this... ENGLISH <DIR> 2003-03-28 12:10 W3KE <DIR> 2003-03-28 13:11 W3KS <DIR> 2003-03-28 13:12 WIN51 10 2003-03-25 4:00 WIN51IA 10 2003-03-25 4:00 WIN51IS 10 2003-03-25 4:00 Drive:\ENGLISH\WIN2003 expands to: Drive:\ENGLISH\WIN2003\ENT\I386 Drive:\ENGLISH\WIN2003\STANDARD\I386 And Drive:\W3KE\ just has a system32 folder and the same with Drive:\W3kS\ Thanks in advance!
