The last 4 months I am having a problem with internet attacks . The messages from Isa Server are: "ISA Server detected an all port scan attack from Internet Protocol (IP) address 62.189.244.229. For more information about this event, see ISA Server Help. " and "ISA Server detected an Internet Protocol (IP) half-scan attack from IP address 216.178.5.2. For more information about this event, see ISA Server Help.". The IP addresses are changing all the time and sometimes the Server is locking itsself. What should I do in order to stop that? Thank you in advance Lymaxis Kostas
