Hello, one of our ISA servers has been hit by a UDP bomb attack as noted in the app log and then a system shutdown occurred a minute earlier. I am assuming the attack succeeded for the hacker, I have since blocked all from that IP addr. I have secured ISA according to the most common guidelines, with Packet filtering enabled and Intrusion Detection turned on. How do I deal with this type of attack any recommendations would be appreciated, thanks. ********************************************************* Sundance Development & Technologies Peter Forster M.C.S.E.
