Subject: Re: Is ping only supposed to work for admin accounts?

Yes.  Ping needs admin rights in all operating systems, but they have
various ways to allow access, such as running suid in unix or using a
special API call on Windows.  If you need ping from cygwin, it's best
to rely on the Windows version without installing the cygwin one.
