Cant access Hyper-VM from Hyper-V manager

I have a few VM's running under Win 2008 (not 2008R2) Hyper-V.  These 3 Windows VM's have been running for years.  One of the VM's suddenly cant be remotely controlled from Hyper-V Manager.  You double click the mini running image and instead of it opening up the console for that VM, you get  "Timed Out while trying to connect to the virtual machine. Try to connect again.  If the problem persists, contact your sys admin.  Would you like to try to connect again"

This VM is running fine and fully accessible from Remote Desktop.

The Host is Win 2008.  The VM is Win 2003.  I have tried from Hyper-V manager on the Host as well as from a Win 7 workstation.

From both the above Hyper-V managers, I have full remote control access to the other 2 VM's that are running just not this 3rd.

Reboot the host.

Follow below action plan :
1. Shutdown the VM.
2. Detach VHD files from VM.
3. Create New VM with same configuration.
4. Attach VHD files to new VM and power on the VM.

I think there might be a VM configuration file issue i.e. xml file , as all other VM are able to connect using Hyper-V console.
