Symptoms

Assume that you start a Windows Explorer (Explorer.exe) process in Separate mode on a computer that is running Windows Vista or Windows Server 2008. Then, you map a new network drive or disconnect an existing network drive in this Explorer.exe process. In this situation, the network drive mapping status is not updated.Note This issue occurs even if you try to manually update the network drive mapping status.

Cause

This issue occurs because Explorer.exe cannot create a desktop window if it is running in Separate mode.Without a desktop window, the Shell32.dll module must enumerate all the drives in order to display a new network drive mapping status. To do this, the Shell32.dll module first detects whether a desktop window is present or not. However, if there is no desktop window and the Shell32.dll module is running in the Explorer.exe process, the function that determines whether to enumerate the drives assumes that Explorer.exe starts a new desktop window. Therefore, the Shell32.dll module does not enumerate the drives, but Explorer.exe that is running in Separate mode cannot create a new desktop window. In this situation, the network drive mapping status is not updated.
