Receipt of such a packet would cause CPU utilization on the server to reach 100%, and thus make the server unresponsive. The Winsock Proxy service and Microsoft Firewall service work with FTP, telnet, mail, news, Internet Relay Chat (IRC), or other client applications that are compatible with Windows Sockets (Winsock). These services allow these applications to perform as if they were directly connected to the Internet. These services redirect the necessary communications functions to a Proxy Server 2.0 or ISA Server computer, thus establishing a communication path from the internal application to the Internet through it.
