PowerChute Network Shutdown Appliance: Event logs for host shutdown and maintenance mode are disappearing after PCNS restart

Issue:
Event logs for host shutdown and maintenance mode are disappearing after a PowerChute restart.

Products:
PowerChute Network Shutdown v4.3 and 4.4.2

Note: We recommend you install PowerChute version 4.4.3 and configure that, and discontinue the usage of the older version. Powershell and the PowerCLI have been preinstalled on PowerChute version 4.4.3, so when reviewing the script instruction, you can skip to the section to download settings.txt, disable_HA.ps1, and enable_HA.ps1 files.

Environment:

Cause:
Hard shutdown of PowerChute Network Shutdown Appliance when the host goes down.

Solution:
