Cause

• The network adapter was ejected from the Windows guest operating system.

Resolution

• Add a new network adapter to the virtual machine .For detailed steps, refer Add a Network Adapter to a Virtual Machine
• If you need to prevent network adapters from being hot-added in the future, disable the Hot-Add feature in the VM’s settings. Refer Disabling the HotAdd/HotPlug capability in virtual machines.
