Consider the following scenario:
Virtual Machine Manager failed to connect to the virtual machine because of a socket connection error. Check the firewall and network settings, and then try to connect again.
This issue may occur because the SCVMM 2008 Administrator Console tries to establish a Remote Desktop connection by not using a VMConnect connection to the Hyper-V host on the 2179 TCP port. Instead, the SCVMM 2008 Administrator Console tries to establish a Remote Desktop connection directly with the operating system of the VM on the 3389 TCP port.
Note The SCVMM 2008 Administrator Console works as expected on a computer that is running a supported version of Windows XP, of Windows Vista, or of Windows Server 2008.
To resolve this issue on a computer that is running Windows 7 or Windows Server 2008 R2, you must use Microsoft System Center Virtual Machine Manager (SCVMM) 2008 R2.
Additionally, you must use SCVMM 2008 R2 to manage Windows Server 2008 R2 Hyper-V hosts.
