Hello,

I have Windows 2003 on HP server. The problem is what sometimes Windows start blacklisting some of LAN IP addresses and not at once it's randomly... After that I can't use any of services on Windows from that computers and I just change client IP everything works fine...

On the server side I can ping blocked IPs, but I can't ping any of my NIC ip or 127.0.0.1

Windows firewall is turned off. No 3rd party firewalls...

What I think it was... After one restart Windows 2003 pop-up message like Syn DoS protection is not enabled to enable click Yes, and after this everything went wrong...

Those sites explain the registry setting that enables syn Dos protection.

There could be a GUI setting but I don't know where it is.

I've already disabled DoS protections in registry. But nothing new...

Do You know is there some GUI about this?
