I checked the logging options and found it set to the first option, MSDE, I don't know why it changed but I don't mind it if I know how to open these log files? Also how to return the logs of the IPEX where the intrustion detection and other packet filter logs are? One last thing please when I go to the logging tab I click start query and all these traffic start appearing, does this affect performance? Should I not do that? because I start query for the firewall and web proxy and leave it all the time. thnx rubix -----Original Message----- From: Thomas W Shinder [mailto:tshinder@xxxxxxxxxxx] Sent: Sat 12/4/2004 4:55 PM To: [ISAserver.org Discussion List] Cc: Subject: [isalist] RE: log files http://www.ISAserver.org Hi TX, You're using the ISA firewall's advanced logging feature?
