Help!

I need to call GetAdaptersInfo from VC++ however the software
that Microsoft is supposed to provide for doing that is no longer
available from their website. Everyone says I need the file
iBldEnv.exe to get the .h and library files but it is nowhere.

I don't want to use some file from taiwan or someplace. I need
the M$ file.

But where to get it?
Or is GetAdaptersInfo no longer supported?

Any help appreciated.
