Answer 1

Hi Naresh Bhatt,

On the worker node, look for logs at: *%CCP_HOME%\Data\Logs*

Event Viewer → Applications and Services Logs → Microsoft → HPC

Look for errors like:

Authentication failures

WCF endpoint issues

Connection timeouts

=> A common but subtle issue: duplicate machine names in DNS or AD can cause issues with trust and connectivity.

=> If the issue persists, enable verbose logging for HPC Node Manager => Edit the configuration file:

C:\Program Files\Microsoft HPC Pack 2019\Bin\HpcNodeManager.exe.config

Add logging config or increase logging level then restart service and observe logs.
