DFS Namespace

Hi, I just setup two new DC's in our organization and I set up DFS and replication and it all seems to be working ok.  We are using DFS as a fail over so I only want people to access the 2nd DC if the first one is down.  The question i have is how do i setup the name space servers?  Right now I only have the 1st DC as the namespace server but I would assume I need to add the second as a fail over?  How do I accomplish this and make sure that all users use the 1st DC.

Thanks for any help!!

DCs are functioning as a distributed query for AD auth by design.

Your name space must have multiple targets. Your referral configuration is how you can alter the client access distribution from round robin, to defining DC1 as the principal target with the other as a failover.

Ok I think I understand, when you say multiple targets do you mean multiple namespace servers?  I have setup a test DFS folder.  I added the two name servers and went to advanced to override referral ordering.  I made the 2nd DC last.  Is this correct?

Yes, multiple servers that will hold the share.  Yes, it will refer all users to the first and in its absence will go to the second.  

Test it out.  Look at computer management on each and you should see all systems connecting to the primary and will be displayed in the shared session list. Power off/reboot the primary and you should see all shift to the other.
