Symptoms
Consider the following scenario:
-
You have a computer that is running Windows 8.1, Windows Server 2012 R2, Windows 8 or Windows Server 2012.
-
You configure the value of the EnableLinkedConnections registry entry to 1 to enable elevated processes to access network shares.
-
You try to map a drive to a nested share by using an elevated token on the computer. For example, you try to map a drive to the following share path:
\\computername\share\myshare\user
In this scenario, the drive is unexpectedly mapped to the root of the nested share. For example, the drive is unexpectedly mapped to the following path:
\\computername\share
Cause
This issue occurs because the code that is used to create the symbolic link does not append the prefixed name of the target to the name of the linked target during the link target name construction process.
