If your are NOT using NTFS for your NT's system dir, try to copy a normal
kernel32.dll and gdi32.dll from other NT4 + SPn (n should be your previous
SP number before SP6) platforms.
RichWin did a very dirty thing here. It renamed the original kernel32.dll to
lernel32.dll and gdi32.dll to hdi32.dll. Then put its own dll wrappers
there.
Good luck !
