DDoS Protection with RegEdit

Ok စရေအာင္ ေအာက္က ပတ္လမ္းေတြကိုလ ုိက္ျပန္ေပးပါ..


(Start--->RUN--->Regedit)


Goto HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Win dows
Under Windows, add a new key called Psched, it may already be there.
Under the key Psched, add a DWORD value named "MaxOutstandingSends" without quotes, of course.
Once you have created the DWORD value named MaxOutstandingSends, right click on it and click modify.
Under value data, put 65535. Under base, Hexadecimal should be chosen.
Here's a few other registry values/keys to stop DoS/DDoS attacks in the event that you have a weak connection and your system can't even withstand 65535 connections:

[HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVIC ES\TCPIP\PARAMETERS]
"SYNAACKPROTECT"=DWORD:00000002
"TCPMAATARETRANSMISSIONS"=DWORD
"TCPMAXHALFOPEN"=DWORD:64
"TCPMAXHALFOPENRETRIED"=DWORD:50
"TCPMAXPORTSEXHAUSTED"=DWORD:1
"TCPMAXCONNECTRESPONERETRANSMISSIONS"=DWORD:2
"ENABLEDEADGWDETECT"=DWORD:0
"ENABLEPMTUDISCOVERY"=DWORD:0
"KEEPALIVETIME"=DWORD00000
"ALLOWUNQUALIFIEDQUERY"=DWORD:0
"DISABLEDYNAMICUPDATE"=DWORD:1

Now All of ok.
