Windows Sockets (Winsock) Problems

Windows 2000 installations where Service Pack 1 (SP1) has been applied, may incur Winsock problems. Calls to the Socket function may not be returned, causing the creation of sockets to fail. When socket programs become unresponsive it can cause 100 percent CPU usage.

WinSock, short for Windows Sockets, is a standard developed jointly by Microsoft, FTP Software, JSB Corp., and SunSelect which enables networking applications to run under Microsoft Windows.
