Syn_Recievd on port 80 , IIS 7.5
- by Ashian
Hi
I have a trouble on my windows 2008 server. I host several web site on it. From some days ago, my web sites stop responding on port 80 after a while.
In this time I can't access web sites from local machine and from remote. I can also browse websites on other ports ( custom port that I set)
I find that I have many Syn_Received status on netstat. And when web sites stop, I got only syn_received on port 80.
I have to restart server because when I try to restart IIS , it takes a long time to stop W3SVC and many times it doesn’t stop at all.
Would anyone please tell me :
- How can I manage Syn Attack ?
Thanks
