Hello Guys,

We have 4 servers in total:

2 x DCs + File Servers
1 x Application Server (Member)
1 x Exchange Server (Member)

We would like to setup DFS-R on the two File Servers which are also the DCs.  We are looking to achieve continuity in case one of the DCs/FileServers go down.  All servers are situated at one site.

I have probably read every article on the web regarding DFS-R and rather then understanding have ended up confuse myself..

I wanted to know which server shall I use to setup namespace and I wanted to be able to access to data even if one of the server is switched off.

Create the DFS namespace on one of your DCs. Add the other DC as an additional namespace server to the existing namespace. Use the DFS namespace for ALL of your drive mappings and file paths. The namespace path should be like \\domain.local\dfs\folder1.

Setup DFS replication when you are done configuring the structure of the namespace. You should, however leave the links to one of the servers disabled. The reason is that DFS doesn't have a way to globally handle file locking and what can happen is that two users can work on the same document but on the two different servers without knowing it and only the version of the document that was saved last will get kept. If the DFS points to only a single available copy you won't have this problem. You can quickly activate the DFS links to the other server should the primary one go down.

Thanks for your helpful response..

Please see the attached dump screen of my DFS settings so far.. I am slightly confused in that how to add the second DC as an additonal namespace server?  Because when I try to create the namespace on the SERVERDFS2 with the same name as I have create on SERVERDFS1 it says it already exists in the domain..  Therefore, if primary nameserver goes down how would the data accessible from SERVERDFS2?
