    I have a small server hosted on windows 2003 standard ed sp1 and since few days ago someone is flooding us through udp ports.

    I have followed these guides




    but the upd flood still goes on.

    I'm using outpostfirewall to see the packets and the ip that are flooding. svchost.exe is shown as flooded through UDP 123 port

    Could anyone help me to sort this out?

    Thank you

    Do you currently have your server configured to match time with the network via NTP? If not, turn the service off and simply shut down UDP/123 at your firewall.
