Symptoms


When a local user logs onto a Windows 8.1 or  Windows Server 2012 R2-based computer, a Microsoft-Windows-AppReadiness event ID 215 error is received.

Note The event log varies slightly, depending on the operating system. 

For example, the following event log is received if the computer is running Windows Server 2012 R2:

The following event log is received if the computer is running Windows 8.1:
Log Name: Microsoft-Windows-AppReadiness/Admin
Source: Microsoft-Windows-AppReadiness
Date: date
Event ID: 215
Task Category: (1)
Level: Error

User: SYSTEM
Computer: computer
Description:
'ART:ResolveStoreCategories' failed for Local_Users. Error: 'The network location cannot be reached. For information about network troubleshooting, see Windows Help.' (0.2968801 seconds)

Cause


The issue occurs because the AppReadiness service queries the Microsoft Store for the category names that are associated with the Microsoft Store Apps installed on the computer when a user logs on for the first time. 

The AppReadiness service generates the event logs if the task that obtains the category names fails. A local user account does not have an associated Microsoft account to be used to connect to the Microsoft Store to retrieve the requested data. Therefore, when a local user logs on, the issue that is described in the Symptoms section occurs.

Note The category name is used when you sort Apps by category in the All Apps view of the Start screen. The All Apps view is opened when you click the down arrow button near the bottom of the Start screen. 

Resolution


This error can be safely ignored.
