I tried a socket application in C#(windows XP 2002). I used 1900 port with
UDP protocal to receive msg from my client application(multi casting). The
receiving application is giving some problem.. like "Only one usage of each
socket address (protocol/network address/port) is normally permitted" . I
didn't write sending in my application ..the application only receive the
message. When I am binding the port that time i am getting this error..

I feel some service(s) may using this same port ... so that this is
happening..give me your idea to reuse the port.. to receive message.

Yes, you are using some port that another app is already using. Try running
netstat to see.

Thanks Chad Z. Hower aka Kudzu,
I got it... we have a Socket Option ReuseAddress property to use the port
which is already accessing by other application.

By setting this property we can use the port before the OS releasing port.
It is not required to wait to release the port.

Yes - but if another application is STILL using that port, now you have
trouble. The OS will randomly distribute connections between the two
different processes.
