Hyper-V Virtual Windows Server 2008 - cannot see network

I have a Windows Server 2008 R2 and using Hyper-V I created a Virtual Machine (again Windows Server 2008 R2). I can connect to it from the Hyper-V but it cannot see the network or the Internet or pinged it.

I have given it a static IP in the router and put that into the TCPIP settings V4. I have checked the MAC address is the same.

In the system tray it says “Unidentified Network – No Internet Access”

I have turned off the Windows Fire wall in case that is interfering.

I have set the Workgroup to be the same as the other machines.

I have been into Hyper-V to the Virtual Machine Manager and created a New Virtual Network, connection type External using HP “NC326i PCIe DualPort Gigabit server adapter”. I have enabled virtual LAN identification. There is also a second adapter “HP NC326i PCIe DualPort Gigabit server adapter #2” but using this I loose the connection to the server on the Remote desktop, the connection is not enabled on the host server

How do I get the virtual machine to see the network?

Your help appreciated

do you have the most up to date drivers for your NICs, was it ever working and all of a sudden stopped? do you have any antivirus or other sort of monitoring software on it?

have a quick look here:

Can you post a screen shot for the Virtual Switch Manager with the virtual switch you created highlighted and showing the connection type and settings?  Easier to visualize...

(Why did you enable VLANs?) Do you use them on your network?

Hi xmlmagician

The driver is up to date

There is no anti-virus on the virtual machine.

The referenced document was very interesting and I have attempted to install RRAS how ever I cant Configure it at the end of the article only the newly created Bridge is visavble?

Hi Leew

Screen shot attached

I enabled VLANs as an experiment, it seemed a resonable thing to try  (though I dont understand it much)

Unchecking Virtual LAN identification makes no difference

The issue seems to have been twi fold

1. I needed to dset up the Virtual Network Before creating the machine
2. I needed a bridge connector between the the virtual network and the real one
