now! i have windows XP pro tcp filteriung on and allow only few ports... 3660 is not among them... still the connection is there,,, futhermore i have made a security policy blocking this addresss and port.. still.. its there,,,
i have also added the dns namepsace to the (restricted site) under internet security for iexplorer.. still connected. my question is : how do I block or stop this connection,, now I have made all this setting and blocking..
