I am actually trying to set up the use of the command line program Robocopy.exe by putting together a consolidated set of files (executable, script files, and help documents) needed to make it do what I want it to do. These command line programs such as ping and robocopy are small program files, and as I learn how to use this new OS, I am trying to learn what unexpected problems and restrictions I encounter in doing what I have easily done in the past. Win 7 has obviously introduced some new barriers which so far seem pretty pointless. The dependencies for ping or robocopy are of course still present in the system file locations, same computer, so they should be findable, but your suggestion that maybe ping and robocopy can't find them is intriguing. However, there is no problem doing what I stated I am trying to do in Windows XP SP3.
