How do I restore network conenctivity for Exchange on Hyper v server

Today power outage damaged a network card on our serrver that hosts Exchange and Terminal server. I replaced the network card and cloned its settings as the original card appeared.
The physical network card is set to DHCP
The Virtual card is set to use the DNS entry for the serrver name which is where I am confused.

Exchange has 192.168.168.14  in DNS and the BDC server (VM HOST) shoudl have 192.168.168.16. When I try to ping BDC server I get a dns lookup of x.x.x.14 then a timeout and response fomr ip 192.168.168.46

Can anyone help me straighten this out, currently all systems are back up but I am not able to get Exchange back up. DNS issues?

Thank you

Go into the Hyper-V server, go to the setting of the VM.
Click on Add Hardware, on the right select Network Adapter and then click on Add button.

Yes, this is an internal adapter for the VM.

The host machine has internet and local access, the issue appears to be witht he VM network configuration.

Install another vNIC, disable the first vNIC and setup with static IP

This would be an internal adapter or external?

When I first logged on to the server and the NIC was bad no lights on it, I suspected hardware.
This NIc has been replaced I am not sure on its original configuration.
The only adapter that was not showing disabled was the vNIC I cloned. I need to have a physical NIC setup for the physical server, correct? and the Vnic set to DHCP since each virtual machine has its own corresponding IP and DNS lookup, is that correct?

James HIT DirectorCommented:
Well, you could use DHCP if you wanted to but it makes sense to statically assign at least the Host server NIC (for management purposes)
Obviously you will need to assign the same static IP for the Exchange VM (to avoid having to re-write your firewall rules).

All IP's should be on the same subnet and gateway.
When you set up the new, add the correct internal static IP (192.168.168.14) and see if you can ping it from the host.
 
If not, then post the results of the ipconfig /all command and let's see where this is failing.
