    Windows: Workaround Win7 SMB Reconnect Bug
    
    The SMB specification permits the server to save a round trip
    in the GSS negotiation by sending an initial security blob.
    Unfortunately, doing so trips a bug in Windows 7 and Server 2008 R2
    whereby the SMB 1.x redirector drops the blob on the floor after
    the first connection to the server and simply attempts to reuse
    the previous authentication context.  This bug can be avoided by
    the server sending no security blob in the SMB_COM_NEGOTIATE
    response.  This forces the client to send an initial GSS init_sec_context
    blob under all circumstances which works around the bug in Microsoft's
    code.
    
    Do not call smb_NegotiateExtendedSecurity(&secBlob, &secBlobLength);
    
    As a result of the SMB 1.x bug, all attempts to reconnect fail due to
    SMB connection resets.  The SMB 1.x redirector will retry indefinitely
    but all processes with outstanding requests to \\AFS will block until
    the machine is rebooted.
