SetSocketOption error

[=?Utf-8?B?aXdkdTE1?=]

hi, im trying to send a broadcast out to my network using a UDP socket. heres
how i initialize it.

Dim soc As New Socket(AddressF amily.InterNetw ork, SocketType.Raw,
ProtocolType.Ud p)

i get the data into a byte array, then i try to set the socket options and
it works fine

soc.SetSocketOp tion(SocketOpti onLevel.Socket, SocketOptionNam e.Broadcast, 1)

however, when i use the SendTo method, it throws a socket exception saying i
am tryibng to access the socket in ways i dont have permissions. i do have
permissions to create sockets (i dont have admin permissions but i have used
sockets on this network before, and im a poweruser). it throws the error at
this line:

soc.BeginSendTo (bt, 0, bt.Length, SocketFlags.Non e, New
IPEndPoint(IPAd dress.Broadcast , PORT), AddressOf CallBack, soc)

PORT is an integer constant with the value of 11000. any help would be
great, thanks

1) Raw Sockets were removed from Windows XPSP2
2) Raw Sockets (when they did exist) requires that the application
have admin privledges.
