I've just installed the firewall client onto my laptop and connected my laptop to my ISA server. However when I try and refrresh it I get the message:- Theserver is not responding when client requests and update. Possible causes: - The server is not an ISA server - The server is down This seems really strange as my desktop PC refreshes fine. I still get internet access through my laptop though and the cabling seems fine as I can browse other pc's on my network. Any ideas ?
