Cluster-Aware Updating (CAU) has detected that Windows Firewall is enabled on node "{0}". However CAU is unable to enable the 'Remote Shutdown' firewall rule group. This will prevent CAU from restarting the node as necessary after updates are installed. Check if Group Policy settings are used to configure Windows Firewall and adjust the policy settings to enable the firewall rule group.
