3rd attempt to send this.
I agree, and typically I’m cleaning up after people too,
but, frankly, I haven’t been able to figure out how to do
this multipathing. I’m usually bit-banging on the HW, not
doing all this OS manipulation crap, and win2k pnp isn’t
helping.
So, if you would kindly send me some well designed
multipathing code- or at least some really in depth ideas-
I promise you won’t have to clean up after me. If not,
well…
