cygwin: not administrator account?

[ping]

experts:
I run into an account priviledge issue here when I tried to setup ssh 
server in cygwin.
I don't remember I ever ran into this previously in winXP.
so this is in my win7 HE.
looks I can't ping anything and can't proceed with sshd activation.
but from control panel I'm sure I'm administrator (I'm the only user  in 
this new laptop so far).
please advice. I'm not sure how I can work with it w/o an ssh server ...
thanks in advance.
