denied request

Hi,
I have written a client-server program using Winsock. I used nonblocking socket (overlapped socket) with WSA...
A client attemps to connect to server. Although server denies that request, that client can not notice that. FD_WRITE and FD_CONNECT are still raised for that client.
I have checked that client socket for writability and I know that it is still valid.
I think there are some problems with my implementation but I can not figure them out.
Help me, please. How can my client know that
its request is denied.

Thanks

I had a similar problem a while ago. Do you call WSAAsyncSelect and in that case when do you call it?
