Question:
My client-server program runs OK on real hardware but crashes on WINS with an access violation at server shutdown. What might be going wrong?

Answer:
Check that after starting your server code on WINS, you make a call to UserSvr::ServerStarted().

// notify the kernel that a server has started.
#if defined (__WINS__)
UserSvr::ServerStarted();
#endif

If you do not do this the DLL implementing your server may be unloaded prematurely, leading to an access violation.
