This document explains How to Enable Access to Network Shares in image 6.5.x
Procedures
Go to Start -> Settings -> Device -> Network ID tab
Check the "Enable Access to Network Shares" and type the default network share path (\\Computer name\Share name\). Note: Computer name must be used when entering the default network share path – IP address will not be accepted. This path will be used as the default network share by the local OS from now on.
Set Network IDAuthentication behavior determines how the device performs user-level authentication while accessing the Default Shared Folder.
Specify whether the device should use the Logged-On user credentials as set through the Authentication Tab or other alternative credentials.
Prompt for Credential if Needed (IE Only) triggers the device to prompt for alternate user credentials incase the ones defined do not match while browsing a web site.
Prompt for Credential if Needed (Domain Only) triggers the device to prompt for alternate user credentials incase the ones defined do not match while browsing for a network resource (e.g. Shared Folder). Note: In case "Prompt for Credentials if needed…" options are not selected. No error message or prompt will be displayed to users in logon failure events.
Restart the device for the changes to take effect.
