Setup WordPress with Windows Server Distributed File System

My Intranet site I created for my work is hosted on Windows Server 2008R2, IIS 7.5, and this server also is a file server, and the server name is fs01. fs01 is also setup with another file server, fs02, as a distributed file system, which means these 2 file servers have what’s called a namespace (which we named ns1) to keep files in sync with each other (it’s basically like a network share but is synced between 2 servers and users only see files in the 1 namespace). My boss is wanting me to setup fs02 with IIS and WordPress and to use the same files that are located on the ns1 namespace. He wants it setup that if fs01 goes down, we can point DNS to fs02 and keep on trucking. I wouldn’t really be able to install WordPress on fs02 since that would create a whole new set of WordPress files. I think I would just have to add the website in IIS and point the directory to the WordPress files stored in the ns1 namespace. My thinking is this could work if the 2 MySQL databases were replicating to each other, and I’d have to edit the config file so it’s pointing to the database on fs02 if we had to switch over. Has anyone heard of doing this?
