Symptoms

Consider the following scenario:

  • You enable the Transparent Caching Group Policy setting on a computer that is running Windows 7 or Windows Server 2008 R2.

  • You access a Distributed File System (DFS) share by using a nested DFS link from the computer.

  • In poor network conditions, the Transparent Caching feature enables shared files to be pinned by using client-side caching (CSC).

In this scenario, DFS network path goes offline and does not come back online.

Cause

This issue occurs because a slow link detection setting transfers the file paths that are pinned by using the Transparent Caching feature to offline.

Note The expected behavior is that the slow link detection setting ignores file paths that are only be pinned by the Transparent Caching feature.
