Products

Issue/Introduction

When running any inventory, Full or Delta, Hardware or Software, the inventory process fails and the following is seen:

An unknown exception was thrown on server side.  
Invalid UUID String

No useful information was found in the Agent Log, even with elevated logging enabled as documented:  Configuring logging on the Notification Server and an Altiris Agent computer

The Event Viewer logs (Application & System) also didn't provide any helpful information.

NOTE: Only one machine out of nearly 1600 was seeing this and they were all running Windows 10 and were basically the same make/model of machine.

Environment

ITMS 8.6 RU3

Resolution

This issue was resolved by:

1. Uninstalling the Sym Agent
2. Deleting the computer record from the database 
3. Reinstalling the Sym Agent and letting all plug-ins be reinstalled also.
