Microsoft also released a hotfix for Hyper-V where you cannot connect to a virtual machine by using the Hyper-V Manager MMC snap-in in Windows Server 2008 R2. The situation is:
“When you try to connect to a Hyper-V virtual machine by using the Hyper-V Manager Microsoft Management Console (MMC) snap-in on a computer that is running Windows Server 2008 R2, you cannot connect to the virtual machine. Additionally, you receive the following error message:
Cannot connect to the virtual machine. Please retry.
Note This issue does not occur when you connect to the Hyper-V virtual machine by using Remote Desktop Services.
This issue is caused by a function failure that occurs when the connection uses the VMconnect.exe command line”.
A supported hotfix is available from Microsoft.

Hi,
I have a hyper-v cluster (2 nodes) and Windows Server 2008 R2. I have an similar issue on both Hyper-V hosts, but my error message reads ‘Cannot connect to the virtual machine. Try to connect again. If the problem persists contact your system administrator. WOuld you like to try again?’. I have checked the certificates and they are valid. Additonally, the event logs state a Hyper-V Worker error:Event ID 12480 : %hostname% faliure in machine remoting system. I haven’t tried the hotfix yet as I am not sure it applies. Can you please offer some advice? Thanks
