;When a TCP connection is closed, the socket-pair is placed into a state known as TIME-WAIT. This is done so
;that a new connection doesnt use the same protocol, source IP address, destination IP address, source port,
;& destination port until enough time has passed to ensure that any segments that may have been misrouted or
;delayed are not delivered unexpectedly. RFC 793 specifies the length of time that the socket-pair should not
;be reused as 2;maximum segment lifetimes (2 MSL), or four minutes. This is the default setting for Windows
;Server 2003 TCP/IP. However, w/ this default setting, some ne2rk applications that perform many outbound
;connects in a short time may use up all available ports before the ports can be recycled. Windows Server
;2003 TCP/IP offers 2 methods of controlling this behavior. First, the TcpTimedWaitDelay registry parameter
;can be used to alter this value. Windows Server 2003 TCP/IP allows it to be set as low as 30 seconds, which
;should not cause problems in most environments. Second, the # of user-accessible ephemeral ports that can be
;used to source outbound connects is configurable using the MaxUserPorts registry parameter. By default,
;when an application requests any socket from the system to use for an outbound call, a port between the
;values of 1024 & 5000 is supplied. The ;MaxUserPorts parameter can be used to set the value of the uppermost
;port that the administrator chooses to allow for outbound connects. For instance, setting this value to
;10,000 (decimal) would make approximately 9000 user ports available for outbound connects. For more details
;on this concept, see RFC 793. See also the MaxFreeTcbs (below next) & MaxHashTableSize (next one after)

;It is important to understand that SOCK_RAW sockets may get many unexpected datagrams. For
;example, a PING program may use SOCK_RAW sockets to send ICMP echo requests. While the

;HOST_UNREACHABLE) may be delivered to this application also. Moreover, if several SOCK_RAW
;sockets are open on a machine at the same time, the same datagrams may be delivered to all the
