I have tried to load XP SP2 and it failed. On restoring my laptop to the earlier Restore Point, Windows does not restart. I get the message 'services.exe - Unable to Locate Component : File NCObjAPI.DLL was not found'
I get this message starting up in all Safe Modes, Last Known good configuration, Debugging etc.
hopefully you should be able to correct this problem by replacing the file in the directory where it should be. if you go to the link below, you will be able to d/l the file...
