When i install Firewall Client Software in client hosts, Firewall Client Software works well windows 2000 professional but in Windows 98 doesn't work well. When i install Firewall Client Software on Windows 98 client host, fter bit minuts instalation the clients hosts did not connected to Isa Server. Any Idea? Best Regards Mario Videira
