1，打开记事本
2，拷贝如下代码

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
"SynAttackProtect"=dword:1
"TcpMaxPortsExhausted"=dword:5
"TcpMaxHalfOpen"=dword:500
"TcpMaxHalfOpenRetried"=dword:400
"TcpMaxConnectResponseRetransmissions"=dword:2
"TcpMaxDataRetransmissions"=dword:2
"EnablePMTUDiscovery"=dword:0
"KeepAliveTime"=dword:300000
"NoNameReleaseOnDemand"=dword:1
"DefaultTTL"=dword:256
"EnableDeadGWDetect"=dword:0
"DisableIPSourceRouting"=dword:1
"EnableFragmentChecking"=dword:1
"EnableMulticastForwarding"=dword:0
"IPEnableRouter"=dword:0

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters]
"EnableICMPRedirect"=dword:0
"EnableDynamicBacklog"=dword:1
"MinimumDynamicBacklog"=dword:20
"MaximumDynamicBacklog"=dword:20000
"DynamicBacklogGrowthDelta"=dword:10

3，另存为"anti-ddos_for_win2003.reg"
4，在需要的机器上双击上面的文件，信息会导入注册表
