What do you do in your OnAccept handler? In particular,
do you try to accept multiple sockets? A test to try is to
reset the event mask of your listening socket each time you
exit its OnAccept handler.

Also, as a reality check - make sure your message loop
never gets stuck... E.g. when you break into the debugger,
almost always you should end up in the message loop.

Hi Alexander.

In OnAccept I just accept one incomming connection, since as
documentation of WSAAsyncSelect says, FD_ACCEPT is posted after an
accept call if there is another connection request available to accept.
BTW, I have tested with a loop in OnAccept handler to accept all pending
connection requests and behaviour did not change.

The problem is that OnAccept handler is not called for a long time
(maybe 1, 2 or even 5 minutes).

OTOH, the first time I open the server socket, everything works fine,
even if there are 50 clients running trying to connect to the server
before I start the server. But after a shutdown/close/create/listen
sequence the problem appears. Maybe has something to do with the Socket
Notification Window creation/destruction by MFC framework?

But ofcourse it seems problem with MFC. No offence, but thats the
reason i hate extra libraries, certainly ATL/STL/MFC etc. are meant
for quick development and prototypes rather for every single
solution.

Julián, how about writing a dll that will implement the server using
standard socket interfaces? And from the code portability prospective
you will be free to write number of interface on top of that
_dll_server_. A simple multi thread server would be doing that all and
use windows messaging for moving data back and forth.

Sure, debugging would be far more easy in this layered approach .
