why has this guy got so many connections? - 212.204.251.30
You definetly have too many connections in TIME_WAIT state similer to a denial of service attack, you need to make sure these registry settings are set, you will need to reboot too.
Look at my attachment rename it to .reg and run it, I am sure I havnt missed anything but PLEASE check the technet site before appling it and make sure YOU are happy with the settings.
