SYMPTOMS
On a computer that is running Microsoft Windows Server 2003, you may receive an event that is similar to the following:
CAUSE
This problem occurs because Microsoft Windows Server 2003 does not support the MaxFreeTWTcbs registry value to control the number of transport control blocks in a time-wait state.
When a Transport Control Protocol (TCP) connection is closed, the socket pair is put in a time-wait state. This state prevents a new connection from immediately using the same protocol, source IP address, destination IP address, source port, and destination port as the closed connection. Therefore, any segments that may have been misrouted or delayed are not delivered unexpectedly.
RFC 793 specifies the length of time that the socket pair may not be reused as two maximum segment lifetimes (MSL), or four minutes. However, with this default setting, network applications that perform many outgoing connections in a short time may use up all available ports before the ports can be recycled.
