MFC Sockets and VISTA Beta2

Dear Newsgroup,

I've got the problem, that CSocket::Create gets the error 0000273F (german
error text: "Es wurde eine Adresse verwendet, die mit dem angeforderten
Protokoll nicht kompatibel ist.")

if the program uses MFC DLL in a shared library with Vista Beta2 (Build
5384).

To reproduce the behaviour:

- create MFC project (I've done it with VC6)
- use MFC in a shared library (_AFXDLL defined!)
- activate Windows Sockets

Put the following code into a function:

-----------------------------------------------------------------
  CSocket *s = new CSocket ();

  if ( 0 == s->Create ( ))
  {

    LPVOID lpMsgBuf;
    DWORD dwErrorNo = GetLastError();

    if ( 0 == dwErrorNo)
      return;

    FormatMessage ( FORMAT_MESSAGE_ALLOCATE_BUFFER |
                    FORMAT_MESSAGE_FROM_SYSTEM |
                    FORMAT_MESSAGE_IGNORE_INSERTS,
                    NULL,
                    dwErrorNo,
                    MAKELANGID ( LANG_NEUTRAL, SUBLANG_DEFAULT),
                    (LPTSTR) &lpMsgBuf,
                    0,
                    NULL);

    CString szMessage;
    szMessage.Format ( "%s (%.8X)", (LPCTSTR)lpMsgBuf, dwErrorNo);

    MessageBox ( szMessage, "huhu", MB_ICONSTOP);
    LocalFree ( lpMsgBuf);

    return;
  }

-----------------------------------------------------------------

Is it a bug in MFC rundll for Vista? I don't want to give up the shared MFC
library (it works, if I do static linking).

Thanks,
Axel.
