If you did not use the import/export feature to move your VHD from Hyper-V server to same server after rebuild or new server you may encounter some issues.
One such issue is that you may receive an error when trying to set the IP address on the guest OS. The message you may receive is "The IP address you have entered for this network adapter is already assigned to another adapter (microsoft Virtual machine Bus Network Adapter) which is no longer present in this computer." To assign the IP you need do the following:
- Go to command prompt and type set devmgr_show_nonpresent_devices=1
- Start device manager by typeing start devmgmt.msc
- In device manager click View>show hidden devices
- Go to Network Adapters and you should see the conflicting device. Remove It.
- You should now be able to assign the IP Address.
Next time it's best to use the Import/Export feature.
UPDATE:
The issue I ran into can be avoided by first uninstalling the NIC from the guest OS using Device Mager.
