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?
