C# UDP socket timing problem...

Dear all,

what we have to do is send 1 byte by UDP to a destination, after that we
should receive data from there. We implement it already and it works, but we
saw after we created the socket, and try to send out 1 byte, there are 3-5
time a s packet is send over port 137 which we didn't use before our 1 Byte
is send out over the assigned port number. Between each packet on port 137
there is ~1 second delay.

Has anyone any idea where that comes from?

Thanks,
Ingo

137 is the Netbios name resolution service. What kind of address are you using when sending the UDP
packet?
