Max TCP sockets

I'm having problems with an APP server and it appears it is not closing TCP
sockets. SO...
My question...

What is the max TCP sockets for Win2k3? I found the registry key on a XP
workstation and it seems that post SP2 65534 was set as the default but could
be increased to something over a mil. I would assume that server would be
all of that.
Anyone know?

No, but for security (to keep from killing the server with a syn atack) the
availabe ports got massivily restircted in some service pack versions. I
remeber winxp as being restricked to only ~1024 open ports. So if you have
an app thats doing lots of connect/disconcts you quickly run out of ports
and 'hang' until the tcp_wait time runs out and it can recycle port number.
