Christian found out that some of this problems are caused by missing 
winsock initialisation which has to be in every application in the 
following manner.

    WSADATA wsaData;
    WORD wVersionRequested = MAKEWORD( 2, 2 );
    WSAStartup( wVersionRequested, &wsaData );

Because placing such call in very applications looks very mess and I 
think there must be a way to place this in kdewin32 or kdecore library.

Is anybody there who has an idea where to place this stuff ? In 
KCoreApplication constructor oder somewhere else ?


As Manuel stated above there seems some effort be required to enable ipv6.
