I have several Windows 2000 computers which have a particurlar program installed. On all of them, if you try to use a command line command such as ping, I get '<command> not a recognized internal or external command' unless I cd to c:\winnt\system32 first in which case it works OK. I know that the path statement is correct. I have seen the fix for this here before but cannot find it now. I remember that it involved a simple register hack, something about changing the type I think. Can anyone help me?
