This points even more clearly to asking the standard questino for any
network related stuff - are you running any personal firewall software
(other than the one builtin to windows - that one is known not to be so
troublesome), bandwidth limiters or antivirus that has network scanning
fetures? If so, try uninstalling it (you can first try disabling it, but
quite often you need to uninstall all the way).
(It could still simply be increasing the number of connections too far,
but a broken fw might cause the problem to show up even though it's not
really there)
