Hi All, Sorry my english. I have a lot of win98 clients in my network. When i install o FW Client (Microsoft Firewall Client Version 3.0) in any Win98 Client in my network, i have two situation: - After installation i have my Win98 Client Configured to use Isa Server. When i try to run Internet Explorer my Isa Server is inaccessible, i.e., FW Client is disable. Then, i click on FW Client Icon on task bar and i have FW Client Options. So, i enable Automatically detect ISA Server Option. With that, i am in second situation, that i explain below. - Firewall Client Icon on Task Bar replays that Isa Server could not be detected, and i can navigate for all web sites although are configured to deny in Isa Server Site and Content Rules. Any idea? How can i solve this problem? Thank You Mario Videira
