The RPC Troubleshooting State Information machine setting should be configured correctly. Determines whether the RPC Runtime maintains RPC state information for the system, and how much information it maintains. Basic state information, which consists only of the most commonly needed state data, is required for troubleshooting RPC problems. If you enable this setting, you can use the drop-down box to determine which systems maintain RPC state information. If the setting is disabled or not configured, RPC uses the Auto2 setting.
