Symptoms

Assume that you use Group Policy Preferences (GPP) to manage the mapping of drives in a network environment. Additionally, you set the non-persistent flag when you map a drive on a client computer that is running Windows 7 or Windows Server 2008 R2. However, when the client computer is not connected to the network, the mapped drive is displayed unexpectedly as a disconnected drive in Windows Explorer.

Note This issue does not occur if you use the following command to configure the non-persistent flag or the persistent flag:
NET USE /PERSISTENT:{YES | NO}

Cause

This issue occurs because of an error in GPP that causes it to ignore the non-persistent flag during the drive-mapping process.
