This update addresses an unresponsive program issue in computers running Windows 2000 Service Pack 1 (SP1), and is discussed in Microsoft Knowledge Base (KB) Article Q278522. Download now to ensure that your programs with socket functions (network program identifiers) respond to requests correctly.
This issue exists because there is an error in the way requests are processed on computers that are running Windows 2000 SP1. When a program does not respond to a request for the creation of a socket, the socket is not created, and the program becomes unresponsive. This can result in 100 percent Central Processing Unit (CPU) usage.
