I installed 2 windows servers (2016 Standard) in Hyper-V. In one of them I am not able to add any role. Here is screenshot,
Although some checkboxes are enabled, when I click on them they are not getting checked. Why? What might be the reason for that? The other server is fine. I installed there DNS and Domain Controller.
Edit
I don't know why, but when many virtual machines are running on Hyper-V the Windows Server is behaving the way I described above. I shut down all machines and left the only one then reinstalled the Server. Now the issue disappeared. I have no clue at all why. Anyway, I will look forward if someone can explain this phenomenon.
