Unable to connect to VMs with console

Hi there,

I have a problem with connecting to my VMs using the console. I get this error " The Connection was lost due to a network error...." error code 0x0404, 0x0000.

I'm using SCVMM 2012 SP1.  This error comes instantly, so it's not timing out. If I connect to the Hyper-V host with the Hyper-V Manager, it works flawless. Any ideas on how to fix this?

Cheers
