...or simply add this registry key should the above method somehow fail:

TCP SYN flood attack protection
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
SynAttackProtect
REG_DWORD
2 (recommended)
0 = default; normal protection against SYN attacks
1 = connection times out more quickly
2 = additional timeouts from 1; also limits certain socket options

Setting this value to 1 or 2 will reduce the threat of TCP denial of service attacks.
Denial of service (DoS) attacks cannot be stopped entirely, but this simple registry setting will help reduce the risk.
