Windows XP with SP2 installed limits the number of simultaneous outgoing TCP connections to slow down the potential spread of worms, viruses etc.. Unfortunately this can also affect scanning and monitoring programs like the EventSentry heartbeat monitor.

Additionally, you can adjust various aspects of the Windows TCP stack in the following registry key:


Some of the registry values worth adjusting are:

TcpNumConnections: Maximum number of connections TCP has open at any given time

TcpTimedWaitDelay: Amount of time a connection remains in the TIME_WAIT state


You can find out more about these and other related configuration values by searching at http://technet.microsoft.com or your search engine.
