Found no NIC after the p2v conversion for Hyper-v 2012

Recently, I did a P2V conversion on my old DELL Tower (do not remember the exact model), using MS Disk2VHD utility. The conversion was successful. After that, I copied this VHd file into a MS Windows Server 2012 Hyper-V host. After booting up this Vm, everything looked perfect except NIC, in which no NIC was found. I browsed to the Device Manager, and found no Network adapter, only to see 2 "unknown object" exclamation mark.

This server is loaded with MS Windows 2003 32-bit with Sp2. What's went wrong with the conversion? How to resolve it?

thanks,

It also install missing drivers that are required for Virtual Hardware. (which is what you are missing!).

You may also need to remove the old nics from the system. They may still be present in the system but not showing under network adapters. This has happened to me several times doing VMware P2V's.

If the old devices are still present you will get an error when trying to set the ip address of the new virtual nic.

Hi Hanccocka,

I thought integration services are meant to make the interaction to the VM much better?

Hi xxdcmast,

I'll try it when I am onsite for the next trip.
