Windows Server 2012 R2 DFS, System Error 53

Background Info

- AD is functional level 2008 R2

- Web server is running Windows 2012 + IIS (W1 > W5)

- File Server is running Windows 2012 R2 and DFS (FS1, FS2)

Now when i setup my dfs file share, it is pointing to FS1, during this period, all my web servers (W1 > W5) works fine

However when i add in FS2 to the DFS, i start getting error 53. Mapping directly to the file share works properly, just the DFS not working properly

C:\Windows\debug>net use \\contoso\dfsshared\bank
System error 53 has occurred.

The network path was not found.


C:\Windows\debug>net use \\fs1\bank
The command completed successfully.


C:\Windows\debug>net use \\fs2\bank
The command completed successfully.

Has anyone experienced such an issue before?
