As you may know the WinXP Setup CD's that are already integrated(by Microsoft) with WinXP Sp1 or Sp2 package have a directory called DOTNETFX. This folder contains the necessary setup files of .NET Framework 1.1 and its SP1. The Setup can be triggered via the 2nd page of the AutoRun Menu of the CD by clicking "Install .NET ..." as you also know I want to know is there any way to integrate the KB886903 hotfix which is a patch made for .NET 1.1 Sp1, into this folder without changing the structure of the folder. I have tried some methods(including editing the XPSP.ini,BASELINE.DAT,DFFACT.DAT,VS_SETUP.PDI) but none of them worked. I know there are other ways like making a new package or integrating with the WinXP Setup but i need it in this way.. Thank You..
