The ncecat utility is part of the NCO package, which is developed and maintained by Charlie Zender and his colleagues fro a sourceforge site: http://nco.sourceforge.net/ I don't see any prebuilt binary distributions for Windows there, but it may be possible to build from source pretty easily with a package such as Cygwin.
