DFS 2008 r2 Failover

Hello,
I have 3 servers: 1-DC; 2-File server; 3-Replica/Failover File server. I setup DFS-R replication and it was working but when I unplugged my primary File server from the network, failover didn't work. DFS roles\Features are installed on all 3 servers.
I also tried to create replication in DFS-N and that  didn't work. I need help to understand what am I doing wrong.

Thank you in advance,

sw

Ok DFS is not my specialty but I know enough to help you.
At an overview it works like this

DFS Namespace(consider this like a dns name that users access resources like sharedrives EG \\DFSNAMESPACE\ITSHAREDRIVE)
The DFS Namespace will point to the active or server of the DFS servers.

I would recommend you do the following.
1. Lab this yourself, download 2012 windows server study version setup some DFS servers. I know this is a different OS but it is very similar.
2. Have a read of this https://technet.microsoft.com/en-us/library/cc732863(v=ws.10).aspx
Step by step how to on DFS in 2008R2.
3. I recommend you become farmiliar with this rather than messing around with it, as windows goes it is one of the more advanced features.

I experienced this same thing. My issue was that i was to impatient. The fail over did in fact work but the referral rate was set for an hour so it did not refresh the dns path until then. You can try changing the referral rate to a lower number (For testing i set mine to 30sec)
