An Error Occured While Reconnecting VMware Shared Folders

When trying to access my VMware Shared Folder, I get this error:

An error occurred while reconnecting D: to \\vmware-host\Shared Folders\VMPublic

VMware Shared Folders : The network is not present or not started.

This connection has not been restored.

This is because the VMware Shared Folder is mapped, but not enabled in VMware Workstation or Player. Go to the Settings of the VM and enable VMware Shared Folders (use the Always setting).
