Hi guys! I have a network with Windows 2000 advanced server in the server side. I have ISA Sever 2000 integrated mode and all the client computers have been installed with Firewall Client; but I'm having troubles with the firewall client, because frequently in the client computer's tray appears the red admiration sign over the firewall client icon meaning that ISA server is inaccessible, so, it doesn't permit that programs that use the firewall client (like ICQ, Yahoo! Messenger, etc.) stop functioning and in some occasions I can't access internet too. I hope somebody can help me with this topic. Thanks in advance Cristian Rodriguez Network Administrator
