Error Unable to detect duplicate item for resource (Computer Name). Reason: Failed to discover domain details.

Issue/Introduction

The following errors can occur on a server that is forwarding information to another SMP (Symantec Management Platform) Server:

Source: Altiris.NS.Discovery.DiscoverMachines.GetComputerNameDomain
Description: Failed to discover domain details for 'MachineName' Error: 53

Source: Altiris.Resource.StandardResources.ComputerResource.DetectDuplicateItems
Description: Unable to detect duplicate item for resource MachineName. Reason: Failed to discover domain details for 'MachineName' Error: 53
Assume that resource is non duplicated and continue processing.

Environment

ITMS 8.x

Cause

Before Inventory Forwarding sends up data it checks to see if the resources are retired, and if it is then it saves it as an unmanaged resource so that the information does not get forwarded.  During this save process the SMP Server checks to see if it is a duplicate (because it is essentially saving itself over another record) and this is when the discovery code gets called.  

The process is failing because for whatever reason the SMP Server cannot contact that machine (it may be off or there may be network polices etc in place to prevent it from contacting it) and this warning gets thrown.

Resolution

This is working as designed.
