Network drives aren't mapped correctly from DFS namespace in Windows Server 2012 R2-based RDS server

This article describes an issue that occurs on a Windows Server 2012 R2-based computer that has the Remote Desktop Services (RDS) role installed. You can fix this issue by using the update in this article. Before you install this update, see the Prerequisites section.

Symptoms

Mapped network drives to a DFS share don't work for subsequent users. This issue occurs when the following conditions are true:
  • User Account Control (UAC) is enabled. 
  • The EnableLinkedConnections registry value is set to 1.

For example, user A connects to the RDS server and starts his RD session. At logon, all drives are mapped successfully and user A can see the network drives in Windows Explorer are connected. When user B connects to the RDS Server and logs on, the drives that were already mapped by user A are shown as disconnected in Windows Explorer. The disconnected network drives, which were connected by user A, are also shown as disconnected to all the subsequent users that log on after user A.
