1. Start the ISA server administration console.
2. In the left pane, select Monitoring.
3. In the right pane, select Start Query or Edit Query as necessary.

ISA server cannot contact upstream proxy
The cause may be network issues or firewall rules on the local ISA server or (if the ISA server is not the edge device) on the edge firewall.
