I was just about to run a ping and I got an error saying it was not an internal command. I tried ipconfig, same thing. I remember back a week ago I think I was fooling around with the PATH variable to add a GhostScript program to it. Can someone please tell me the default PATH variable? I want to make sure the essentials are in there. Also, do I add my own paths to the User variables section or the System variables?

Thanks in advance
