Maximum number of concurrent TCP/IP connections - Win XP SP3

Does anyone know what is the maximum number of concurrent TCP/IP connections on Windows XP SP3? I am trying to load test a machine and would like to know what is the max number of tcp connections that can be opened by an application (in my case, java application) towards that machine.

Note that often you may be limited by the number of outbound connections supported on the client machine rather than by the number of concurrent connections possible. See this Socket Bind Error for how to tune MAX_USER_PORT to enable more outbound connections from the machine running the tests.
