arr

I have 3 IIS web servers in an ARR web farm. When we do rolling releases, we take one server offline as a backup server and move it into an "Unavailable State" I have noticed that with ARR, servers will not stay in this state...they come back online automatically hours or days later. Does anyone know how to remedy this situation? This is very bad as the server that is down is typically not running the correct version of our code.

I need to keep a server unavailable until i tell it otherwise.
