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 in KB 179702.

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

Cause

This issue was resolved by uninstalling the Sym Agent, deleting the computer record from the database, and then reinstalling the Sym Agent and letting all plug-ins be reinstalled also.
