Microsoft has released a hotfix for Windows Server 2008 R2 SP1 Hyper-V for when you cannot open the Hyper-V Settings dialog box on a Hyper-V host.
Consider the following scenario:
- You enable Microsoft RemoteFX on a Hyper-V server that is running Windows Server 2008 R2 Service Pack 1 (SP1).
- You create a long logon banner on the server by changing the Group Policy settings.
- You connect to the server by using a Remote Desktop Protocol (RDP) connection.
- You try to open the Hyper-V Settings dialog box.
In this scenario, you cannot open the Hyper-V Settings dialog box.
This issue occurs because a worker session cannot display or dismiss long logon banners when RemoteFX is enabled.
