How to make a Domain DFS redundant in case the main DC goes down

Hi,
I asked that question before but we still have troubles with it. And today I did some testing and as soon as my main dc is turn off, the DFS freezes. Users's computers freezes because their Z: drive that points to \\mycie\masterfolder is unavalable. When I go in the DFS snapin it tells me RPC server unavailable. I had noticed that on my DC1 there was a share that contains all dfs links and dc2 didn't so I created the share and copied all subfolders to it but still it dont work.
I really tought the whole DFS think was hosted in the AD not propriatary to one domain controller.

Here's the rest of my previous question...
Hi,
Is there a way to have a Domain DFS redondant by using two domain controllers.
And I don't mean to have every node with two links pointing on two different servers, but have the dfs structure  still be available when a domain controller goes down.

That's the only way that your DFS is going to be redundant.
If you only have one link, then how will your data be accessible to users?

The native DFS shares on AD, sysvol and netlogon function exactly the same way.
The DFS share information may be stored in AD, but the data needs to exist on accessible media.

Here's how I did it:
So the problem was that on the main DC there was a share with the name of my DFS Root name = Masterfolder but not on the second DC

You open DFS, and then you see at the top "Distributed File Sytem" and right underneath you see "\\yourdomain.com\Masterfolder"
Click on this and in the right side you will see only one "Root Target" which is DC1
Add a new "Root Target" and select the second DC.
Once created you will see \\dc1\Masterfolder and \\dc2\Masterfolder
Now you need to activate the replication and select to replicate those 2 "Root Target".
One think I was not sure by enabling replications on the Root Target was if it would start replications un sub Targets but it does not, it will only replicate the 2 "Root Target" with each other.

Thanks dvt_localboy for your comments but there was too much information missing so I added them after testing it in a lab
