But I'd like to see ntwhich in any case. Maybe this should be renamed VS2003/VS2005 environment differences? Here's another one: hcw doesn't exist in VS2005 so the leash help doesn't build. [mayer@ntp.isc.org - Thu Dec 20 22:37:25 2007]: On an advisory note try running ntwhich on mkdir and see where it finds it. That may tell you why you are having a problem. If you need a copy, send me mail. I have a bunch of tools like that which are not cygwin based.
