Hi Guys, Since I upgraded my isa server to an array, intrusion detection is no longer working. Any ideas why? packet filtering is enabled Intrusion detection is enabled IP Routing is enabled filtering of IP options and IP fragments is enabled All attacks are selected and off course In applications filters DNS Intrusion and POP intrusion are enabled. But for example port scans are not showing in the monitoring, alerts section Anybody? Best regards Remy Plagmeijer, MCSE
