Packet Sniffing error [Wireshark etc]

Wireshark doesn't work for my Win7 PC. Neither does WinDump or any other method. For example I have this code in C#

Code:

mainSocket = new Socket(AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.IP);
 mainSocket.Bind(new IPEndPoint(IPAddress.Parse(cmbInterfaces.Text), 0));
mainSocket.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.HeaderIncluded, true);
byte[] byTrue = new byte[4] { 1, 0, 0, 0 };
byte[] byOut = new byte[4] { 0, 0, 0, 0 }; //Capture outgoing packets
mainSocket.IOControl(IOControlCode.ReceiveAll, byTrue, byOut);

Which should start a simple socket to listen to all incoming packets. I get an exception thrown (SocketException) on IOControl. If I change the parameters it runs, but it doesn't do what I want.

Using winsock2.h in a C++ attempt, doesn't work either (gives an error when I bind). So The above code works for a WinXP PC I have, but not on this Win7 PC I have. I am guessing it is a general problem.

Any ideas? I am running them as administrator of course in Win7/Vista

Nmap Hackers: Microsoft Tightens the Noose on Raw Sockets

Well, they haven't backed down this time! I know that some of you
have been avoiding SP2 to keep your system fully functional. MS made
a blocking tool available to Enterprises, but they overrode it on
April 12 and forced the upgrade through Automatic Update anyway[2].
And now they have quietly snuck the raw sockets restriction in with
their latest critical security patch (MS05-019). The loophole that
allowed users to defeat the limitation by stopping the ICS service has
also been closed by MS05-019. I have appended an informative
NTBugtraq post by Robin Keir on this topic. Pick your poison: Install
MS05-019 and cripple your OS, or ignore the hotfix and remain
vulnerable to remote code execution and DoS.

i believe they stopped the use of raw sockets in win7 and that is why wireshark does not work for you. meow. also know the above is proof that they snuck in rogue code to disable raw socks.
