I recently upgraded a server from server 2008 sp2 to r2. It had hyper-v installed and the Hyper-v machines are working, managed from any other servers. But in Server Manager on the actual machine, if you click on Roles or Features it try to load the screen but then comes up with failed to refresh.
The Error the comes up on Event viewer Applications and Services logs - Microsoft - Windows - ServerManager - Operational is below.
Source = ServerManager Event ID=1601
Could not discover the state of the system. An unexpected exception was found:
