From what little information you have given me, I presume your server is being DDOS'd. Really there's not too much you can do about this if your running a home-hosted server. If you are being hosted by a dedicated server, VPS or SA-MP host then you might want to talk to them about getting network level protection or a firewall, there are several prevention tools however most of them won't be practical to use on your computer.
