DFS – The namespace cannot be queried. The network address is invalid.

by

Problem:

While playing around with DFS on Windows Server 2016 in my lab environment I kept getting the message “The namespace cannot be queried. The network address is invalid” when trying to add a new namespace via the wizard.

Solution:

It turns out DNS in my lab environment was a bit messed up, I was unable to ping the domain. After I corrected my DNS issues the process of creating a DFS namespace completed normally.

  1. One thing to note with environments with Multiple domain controllers , DFS data is stored on the PDC ( Primary Domain Controller ) , make sure you can also ping the server responsible for this role , can you found using

    NetDOM /query FSMO
