Symptoms
Consider the following scenario:
-
You have a Distributed File System Namespace (DFSN) that consists of two file servers.Note The file servers can be either Windows-based or third party-based. For example, the file servers can be Windows Server 2008 R2-based servers or Samba servers.
-
You create a share on each file server.
-
You select the No files or programs from the shared folder are available offline option in the Properties dialog box of each share folder if the file servers are Windows-based and support the Offline Files feature.Note This operation prevents the client computers from performing offline caching on the contents of each share folder.
-
You create a new DFS folder within the DFSN, and then you add the UNC paths of the two shares as the targets of the DFS folder.
-
You enable Client-Side Caching (CSC) on a client computer that is running Windows 7 or Windows Server 2008 R2.
-
You try to browse the DFS folder by using Windows Explorer on the client computer.
In this situation, you receive the following error message intermittently:
An unexpected network error occurred
Additionally, when you open a sub folder, Windows Explorer either does not display the contents of the folder or jumps to the parent folder. This behavior occurs if you have several levels of folders in the share.If you copy files from the DFS folder to the client computer, you receive the following error message:
0x8007003b, An unexpected network error occurred.
Note This issue does not occur if CSC is disabled on the client computer.
Resolution
To resolve this issue, install the hotfix on the client computer that is running Windows 7 or Windows Server 2008 R2.
