Distributed File System (Dfs) is a Windows Server role that enables you to group shared folders that are located on different servers into logically structured namespaces. Just as if they were accessing their local storage. In this article, we shall discuss the steps on how to find Dfs Referral Path and clear Dfs referral Cache. Please see how to Replicate MDT Deployment Share: How to Create a Selection Profile and Link MDT Deployment Shares.
This allows users to have a virtual view of the shared folders, with a single path leading to files that reside on multiple servers.
A referral list in DFS provides information about the available targets (servers). Users accessing a DFS namespace are directed to these targets based on various factors such as load balancing, proximity, and availability.
Note: This is not the target folder where data and contents are stored. Therefore, a folder without a folder target adds structure and hierarchy to the namespace. While folders with folder targets provide users with actual contents.
Therefore, when users browse a folder that has folder targets in the namespace. The client computer receives a referral that transparently redirects the client’s computer to one of the folder targets.

Select the Dfs tab as shown below.
You will see a referral list along with the full path name (server and DFS share name). This will transparently redirect the client’s computer to one of the folder targets.
Without Dfs, system administrators can run out of drive letters because of too many network connections.
Clear DFS Referral Cache On Windows PCs
As discussed above, a referral is an ordered list of targets that a PC receives from a domain controller or namespace server when the user accesses a namespace root or folder with targets in the namespace. You can adjust how long clients cache a referral before requesting a new one.
In this section, I would like to show you how to manually Flush the DFS referral cache via the Dfs properties in Windows and via the Command line.
Browse any of the mapped drives on your PC. Right-click on the file or folder and choose properties as shown below.
Next, select the Dfs tab as shown below. Click on Clear History as shown below. This action requires administrative rights.

Dfs trees make network access easier for users, who no longer have to manually locate which server data is stored on. After connecting to the root of the Dfs tree.
Users can browse for and access all resources contained within the tree, regardless of where the resources are located.
– If a server crashes or must be replaced, or a volume must be moved from one server to another. Users do not need to be notified of the change. An administrator simply modifies the Dfs tree to refer to the new server location and users continue to use the same Dfs path to access resources.
When a user views the contents of a root volume, they see the leaf volumes located under the root and the contents of the shared folder that comprises the root. Users can still use conventional \servernamesharename syntax to access shared folders that are part of Dfs trees.
