Backup Exec 2012 backup and convert to Virtual Machine

This kind of scenario is affected by plug and play

Basically static IP addressing is linked to the hardware identifier of the NIC

If you restore an operating system to different hardware, plug and play kicks in and identifies the new hardware.

This new hardware will have a different identifier and therefofre not be linekd to the static IP address as this remains assigned to the hardware identifier for the NIC that is no longer present.

This means that the network cards in the restored system will end up configured with default settings ( in other words DHCP ) and you will have to manually change them. Because the old ip address is still in the registry as assigned to the original NIC you typically would also see a warning when you try to configure the new card with the old ip address because the operating system is aware that the address is already stored in it's configuration even though it is inactive.

As this is more of an OS thing than a BE thing I would expect BE and VM convertor to show the same symptoms,.

Note you would see the same thing if you shutdown a server, take the existing network card out of the server and fit a new one in (even if this new card is the same make and model as the one you removed)
