I don't know what I'm doing wrong, but everytime I have tried doing a slipstreamed WinXP with SP2, under the installation it ask for SP1 CD. I use a modified winnt.sif for unattended install and have even tried maken a new winnt.sif with the new SP2 deployment tool but still the same. I have tried first updating the slipstreamed disk with first SP1 and then SP2, but again the same. Would apprisiate any help on making a slipstreamed cd as unattended install. Cheers, Stenn
