I recently experienced an error in my Altiris Log Viewer that came up every 30 min when it was scheduled to run.
Failed to find audit ini file at C:\Program Files\Altiris\Altiris Agent\auditpls.ini
Process: AeXNSAgent.exe (116)
Thread ID: 632
Description: Failed to find audit ini file at C:\Program Files\Altiris\Altiris Agent\auditpls.ini
Error was resolved by applying the following settings in the Notification Server:
Configuration>Solution Settings>Software Management>Application Metering>Application Metering Solution Configuration.
There is a section titled Inventory Solution Integration.
Select "Client Based Inventory Solution" and Apply.
This will fix the error and prevent the error messages from appearing in the Altiris Log Viewer again.
