I've been running a Server Essentials 2012 R2 single server for 2 years, it's been reliable so far. Our business is beginning to outgrow, and I have recently added a second production server running Server 2012 R2, (eval version)
My first thought was to set the second server up as a second domain controller with AD integrated DNS for availability. Reading through MS literature it seems as though this doesn't violate the Essentials requirements as this isn't a Read-Only controller. DNS will only resolve on the Essentials server though, I get nothing from the second server.
I added AD DS, promoted the second server to a DC, added AD integrated DNS. I can resolve DNS from both servers on the new server, but the Essentials server will only see itself.
The forums all indicate this is possible, so what am I missing?
