I am getting following error:-
C:\>ping::1
The filename, directory name, or volume label syntax is incorrect.
C:\>ping ::1
Ping request could not find host ::1. Please check the name and try again.
C:\>
First things first. There's a space between the syntax ping and the '::!' bit (read without quotation marks).
Next_virus, seeing your post, looks like you did not add the space. Try it with the space.
For the rest, I tried it on Windows 7. Haven't tried it on any other operating systems, including Windows XP. But it would be a nice idea to look up any other alternatives for those OS as well.
Cheers
