I have worked on a unattended XP installation with nLite. After I have installed the machine boots and tells me Windows is working with "non-certified files" and I should put in the Service Pack 2 cd-rom into the machine so it can recover the proper/secure SP2 files. The terms are translated from Dutch so perhaps in English it uses different terminology as I do. When I use the vendor files set that is not been worked on with nLite, this problem does not occur. Which component shoul I therefor not remove using nLite or is ot something else. Regards 7 thx
