A big thanks !
Just to say thank you to all the people who give me some help and support this week end regarding the mess I had with some SYN flood attack.
The registry tweak worked fine. So now the site is working well again, but a big but here, the attacker still continue is dirty job.
Thankfully the Firewall block well everything, but it's quite amazing that nothing can be done against such assholes.
Great community :-)
