Command-line instructions like dir x: work as expected.

In Windows Explorer, why do these 3 mapped drives not show up? Suggestions and diagnostic questions are appreciated.

  • did you run the CMD as admin? – TomEus Apr 16 '16 at 6:28
  • Good question: CMD was run as admin. In the past I have had success without invoking as admin. Perhaps something was done / configured to prevent network drives from appearing in file explorer? – gatorback Apr 16 '16 at 15:22

Mapped network drives created by an elevated process will not be visible to an unelevated process and vice versa. This has been the case since Windows Vista. Since Explorer doesn't run elevated (unless you fully disable UAC), it doesn't see the drives you made with your administrative command prompt.

To disable that isolation, you can modify the Registry, as instructed by this TechNet article. Navigate to this key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System

Create a DWORD entry named EnableLinkedConnections with a value of 1. Reboot the computer. Network drives mapped by the same user, even under different security contexts, will always appear to programs running as that user.
