1. You need SP1 installed on Windows Server 2008 R2
2. What OS is that? Do you have an agent policy?
3. Do you have deployments seats available? Help > About would show this. You could be out of Server licenses.
-The issue occurs on 2008R2 SP1, 2012R2...doesn.t matter the windows version.
-Not sure what is an agent policy....maybe you can suggest where to look.
