In some cases, antivirus software may block the Diagnostics Console from connecting to the Diagnostics Service that is running on a different machine.
If the remote connection fails or no messages are displayed in the Diagnostics Console, make sure there are no antivirus or firewall settings that are blocking communications between the Diagnostics Console and the Diagnostics Service. An exception may need to be configured for outbound connections from the Diagnostics Service to allow communication with the Diagnostics Console.
