Microsoft tells us that the functionality is available since "Windows 8.1, Windows Vista". If you're running on a windows server it's supported since "Windows Server 2008".
Have you tried searching in the Windows Updates section for any updates or service packs concerning winsock hotfixes? Additionally you may need to install drivers for your network card, or your motherboard if you're using an integrated NIC.
