Socket Error on instantiation

[OJ]

Hi,
I am using windows xp sp 2 and VS2005 Express editions. Whenever I
create a new socket in either VB or C# using the following code...

VB
Private client As New Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp)

C#
private Socket client = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);

....a SocketException occurs twice as such...

+ EnableBroadcast 'this.client.EnableBroadcast' threw an exception of
type 'System.Net.Sockets.SocketException' bool
{System.Net.Sockets.SocketException}


and...

- MulticastLoopback 'this.client.MulticastLoopback' threw an exception
of type 'System.Net.Sockets.SocketException' bool
{System.Net.Sockets.SocketException}

with ...

ErrorCode 10042 int



Can anyone shed some light on what is happening here? It is not raising
an Exception in my app, but it is preventing any communication using
the socket.....

Thanks,
Oli

ErrorCode 10042 int

Google quickly tells us what's going on:

Bad protocol option.
An unknown, invalid or unsupported option or level was specified in a
getsockopt or setsockopt call.

Hi Chris,
thanks for the reply. I saw this too on google. This is happening when
I create a new Socket object from the Dot Net framework. I have
resolved the issue with my procedure and it now appears to work,
although the socketexception still occurs.. I think the problem is that
a TCP stream cannot broadcast like udp so tyhis is "standard"
behaviour...
