PLEASE HELP!!! Scenario: ISA Standard (Integrated) on a Compaq Proliant PIII 550Mhz 384Mb It serves a network with about 150 Firewall clients and runs RRAS for 8 dial-in users. I don't know if it's important to say but it also publishes a Web server sitted in the internal network. All Event Errors were solved, because of the number of errors it sure was a big possibility that it was crashing the service (error 14120). Problem: When I enable IP Filtering (with Intrusion Detection and Routing) it runs smoothly for a while than without generating any error it just crashes. My event viewer has never been so empty. Memory and CPU time seems to be idle. Still have more than 100Mb free. Meanwhile, when the server has IP Filtering disabled it runs smoothly for days. Any help is more than welcome! Tks, Aleksander França Honma
