Ok, I have a new client who has purchased 2 Dell Servers with Windows Server 2012 Std R2. Both servers will be Domain Controllers. My client is a small business with a small budget. He wants the 2 DC's to mirror each other file server wise. If the primary server goes down for any reason he still wants to be able to access the file shares on the secondary DC, until the primary comes backup. So I did some research and it seems as though DFS Namespace/Replication is the way to go. So I setup the Namespace, Folders and Replication. I'm doing all this on 2 VM's to test how the functionailty will work before the servers come in. Now Replication of the data between the 2 servers is working well, but when I took the primary DC down and tried to access the domain share I couldn't. My test domain environment is ; contoso.local. the full UNC path is \\contoso.local\Shares\Folders. I have the share mapped as \\contoso.local\Shares\folder on a Win7 VM. When I brought the primary DC back up I was able to access the domain share. The DFS Namespace is on the primary DC only. Why am I not able to access the domain share when the primary DC is down? I can access the files on the secondary DC by typing \\dc02\Shares\Folder but not using \\contoso.local\Shares\Folder.
