This monitor tracks the status of the HPC Node Manager Service, which is automatically installed on each cluster node to communicate with the HPC Job Scheduler Service. When this service is stopped on a node, task environment variables cannot be set and the node cannot send a heartbeat signal to the HPC Job Scheduler Service.
This error can be caused by any of the following:
The HPC Node Manager Service encountered an error and had to stop running.
The HPC Node Manager Service is disabled.
Group Policy does not allow this service to start.
To troubleshoot and fix this problem:
Restart the HPC Node Manager Service on the target node
Start Event Viewer on the target node and check for any system events from the Service Control Manager or application events from the HPC Node Manager Service. Resolve any errors that are reported by these events.
If the service still cannot be restarted, contact the domain administrator to make sure that this service is not disabled by the domain Group Policy.
If the preceding steps do not resolve the problem, uninstall and reinstall Microsoft HPC Pack on the node.
