It is INCOMPLETE tcp outbound requests. Aka no more syn floods. This will have no effect on the server browser.

It is TCP outbound requests. http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2netwk. mspx#XSLTsection127121120120 What new functionality is added to this feature in Windows XP Service Pack 2? Restricted traffic over raw sockets Detailed description A very small number of Windows applications make use of raw IP sockets, which provide an industry-standard way for applications to create TCP/IP packets with fewer integrity and security checks by the TCP/IP stack. The Windows implementation of TCP/IP still supports receiving traffic on raw IP sockets. However, the ability to send traffic over raw sockets has been restricted in two ways: * TCP data cannot be sent over raw sockets. * UDP datagrams with invalid source addresses cannot be sent over raw sockets. The IP source address for any outgoing UDP datagram must exist on a network interface or the datagram is dropped. Why is this change important? What threats does it help mitigate? This change limits the ability of malicious code to create distributed denial-of-service attacks and limits the ability to send spoofed packets, which are TCP/IP packets with a forged source IP address. Limited number of simultaneous incomplete outbound TCP connection attempts Detailed description The TCP/IP stack now limits the number of simultaneous incomplete outbound TCP connection attempts. After the limit has been reached, subsequent connection attempts are put in a queue and will be resolved at a fixed rate. Under normal operation, when applications are connecting to available hosts at valid IP addresses, no connection rate-limiting will occur. When it does occur, a new event, with ID 4226, appears in the system's event log. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds
