When you change network settings in a Windows virtual machine, you must reset the network stack of the virtual NIC to adopt the new settings. For a Windows guest operating system, you must disable and re-enable the network connection so it adopts a new MAC address. You can do this using the Control Panel.

Procedure

  1. In the Control Panel, navigate to Control Panel > Networks and Internet > Network Connections.
  2. Right-click the network adapter icon and choose disable.
  3. Right-click the network adapter icon and choose enable.
  4. Repeat these steps for each network adapter.
