Disabling ping on Windows Server 2008 to stop DDOS attacks on the server
To disable ping on Windows Server 2008 R2, please follow the steps below:
1) Go to the Start Menu.
2) Select Administrative Tools >> Windows Firewall with Advanced Security -> the firewall will open in a new window.
2) In this window, you will see 'Inbound Rules' - click on it.
3) Under Inbound Rules, please search for 'File and Printer Sharing (Echo Request - ICMPv4-IN)'.
4) Right click on 'File and Printer Sharing (Echo Request - ICMPv4-IN)' and then select Disable Rule.
Once ping requests have been disabled, the ICMP flood goes down and services except ping work fine.
To re-enable the ping, select Enable Rule in the last step.
