Windows XP TCP/IP Connections

Im looking for a way to change the default setting of windows to kill the idle TCP/IP connections. I am running apache HTTP server on windows XP pro machine. Ive tweaked it so I can have 40 connections already but the TCP/IP connections are stuck on TIME_WAIT and I was wondering if there is registry settings or something to kill those connections! It is for a picture server each picture pics up a new thread and is downloaded quickly and the connection needs to drop!
