I was the originator of this article, I have now solved the problem with the gethostbyname() call, which would block and timeout in a couple of minutes (which is not nice). The app is multithreaded, and i needed the app to close when the close box is clicked on (not 2 minutes later). I tried WSACancleBlockingCall() (whatever) and this never cancled the call, so with the help of some more synchronisatoin I found I could use the WSACleanup() call to cancle any blocked calls in any thread. and that works.
