Tcp concurrent connection limit in sp2

Does anyone know how to remove the security limit imposed
my xp sp2 on the number of concurrent tcp connections?
sp2 causes some of my programs to error with the error #
10055 because of this new limitation sp2 implements.

The concurrent connections for SP2 have not been changed:

XP Pro: 10 and XP Home: 5

You're talking about file sharing. SP2 does, in fact, limit TCP connections
in order to prevent trojans from distributing themselves - I remember
reading that somewhere on MS site.

I knew I've seen it somewhere.

"The TCP/IP stack now limits the number of simultaneous incomplete outbound
TCP connection attempts. After the limit has been reached, subsequent
connection attempts are put in a queue and will be resolved at a fixed rate.
Under normal operation, when applications are connecting to available hosts
at valid IP addresses, no connection rate-limiting will occur. When it does
occur, a new event, with ID 4226, appears in the system's event log."

Yes, but notice this DoS attack feature is not the same as the
hard limit on simultaneous connections that NT family non-server
version have always had. The DoS attack rate-limitiing feature is
distinctly different and it can be relaxed.

This site features a safe toll that worked like a charm for me:

How????? I prefer to control the number of outbound connections myself.
