[Winpcap-users] can not get any captured package when apply a filter

[Lin George]

Hello everyone,
I am using Windows Server 2003 x64 version. When using the command WinDump without any parameters, I can get a lot of traffic, but when apply the filter www.google.com by using command,
WinDump host www.google.com
I can not get any traffic captured, any ideas?
thanks in advance,
George
