Hello all, Let me explain further on this problem, on the system tray (Firewall Client)I have intermittent message popup and says that the server is down. But I'm still able to the ISA server to access the Internet. I even try to use the CHKWSP32 utility,same messages.I'm not really good at W2K or windows technologies,so I'm not sure what I can check to verify on this problem. Thank you and regards.
